The Best Bottles of 2024, According to Parents, Experts and Picky Babies
Glass or plastic? Four ounces or eight? We’re demystifying how to choose the best bottle for your baby.

Whether you’re nursing or using a bottle to give your baby pumped milk or formula, feeding your little one can be one of the best opportunities for bonding in parenthood.
But choosing a bottle is complicated. There are a ton of options. Do you want glass, plastic or silicone? What size bottles should you add to your registry? And how many do you actually need? The list of questions feels endless, but we have the answers if you’re planning on bottle feeding, switching from breast milk to formula or just want to be prepared.
We tested dozens of bottles in the real world, spoke to lactation experts and a pediatrician and reviewed feedback from thousands of parents, and we think Dr. Brown’s Options+ are the best baby bottles for most families. They’re loved by parents and experts alike and offer a consistent flow and a patented venting system that many say helps minimize gas and fussiness. And if you’re looking for the best glass baby bottle or the best bottles for breastfed babies, we have top picks in those categories, too—and several more.
Why Trust Babylist?
Babylist is the expert in baby; we know baby gear inside and out. We talk with parents face-to-face in our showroom and on our user panels and hear from thousands of people annually via our Best Baby Products survey. We know what items millions of expecting parents are adding to their baby registries.
As Babylist’s gear editor, I’ve had the opportunity to test out dozens of bottles over the years. I’ve also used bottles to feed my own two children, one of whom was exclusively bottle-fed and one who switched between breast and bottle. Both of these experiences helped me choose the bottles on this list.
For an expert POV, I spoke with physical therapist and International Board Certified Lactation Consultant (IBCLC) Emily Spaeth, founder of Be Well Baby PDX. IBCLCs are the highest accredited healthcare professionals in lactation; they’ve completed years of training requirements including lactation-specific education and hands-on clinical training. I also talked to Kelly Fradin, MD, a pediatrician, writer and New York City-based public health advocate. And I incorporated baby bottle feedback from experts in the trenches: the thousands of parents we heard from through Babylist’s annual Best Baby Products survey of over 6,000 Babylist users along with parents on the Babylist team.

How We Judged
Materials. There’s no “best” baby bottle material—plastic, glass and silicone each have unique pros and cons, so personal preference is the deciding factor for most families. But we wanted to ensure our picks were also durable and didn’t stain or retain any odors over time.
Ease of use. We judged how easy our top baby bottles were to use by factors like ease of assembly, disassembly and cleaning, clearly visible measurement markings and the available options for bottle and nipple sizes.
Performance. Our best baby bottles performed as advertised—no leaks when used properly and, according to our testing and feedback from thousands of Babylist parents, didn’t cause or further aggravate common tummy issues like gas or colic.
We also prioritized these features as we analyzed baby bottles:
Available in multiple sizes
Nipples available in multiple sizes, including slow flow
Durable material
Doesn’t leak when used properly
Easy (enough) to clean
Effective venting system
Easy-to-read measurement markings

Best Baby Bottle Overall
Pros:
- Can help reduce gas & colic
- Popular parent + pediatrician pick
- Can be used with or without venting system
Cons:
- Lots of parts to clean
- Some parents say they leak
- Longer nipples may cause gag reflex for some babies
Over two-thirds of parents—38%, to be exact—named Dr. Brown’s as their favorite bottle in our Best Baby Products survey. They’re also the bottles I used and loved daily for four years with my two boys, one of whom was a preemie with latching issues, and the bottles we think are the best choice for most babies.
Dr. Brown’s claim to fame is their patented venting system. Designed to mimic breastfeeding, it limits your baby’s air intake while drinking, helping to reduce burping, gas, spit-up and even colic in some little ones. Are they a magical solution for every fussy baby? Sadly, no. (But we’ll let you know as soon as we find one.) But enough parents tell us they see a noticeable difference when using Dr. Brown’s that we stand behind their claim. “My three-week-old has not thrown up once, spit up or had bad gas,” one mom noted in our Best Baby Products survey. Dr Brown’s bottles are “the only ones that worked for my baby for the first six months,” another said.
Lactation consultants love Dr. Brown’s bottles because of their consistent flow. “As opposed to some other bottles, Dr. Brown’s uses a laser to create the hole in the nipple,” says IBCLC Spaeth. This differs from other nipples on the market that are made using a needle, she explains, which can lead to inconsistent flow rates. This precise, consistent cut is a big reason she thinks lots of babies take these bottles so well.
The two biggest negatives of these popular bottles are ease of cleaning (or lack thereof) and potential leaking. The first, unfortunately, is unavoidable; the bottle’s venting system has multiple parts, some of which are pretty tiny, and cleaning them does indeed take some time. The upside is that the Options+ system lets you remove the internal venting system as baby develops, leaving you with only a bottle, nipple and a collar to clean. The second issue, leaks, can be solved by a few different methods depending on the reason for the leak. You can check the brand’s FAQ section for solutions, but my biggest learnings from years of use is to remember to always use the Travel Disc and keep the bottle upright when on the go and loosen the collar before warming the bottle to reduce the pressure.
The popular starter set shown here comes with a selection of bottles, nipples, caps and cleaning brushes. And if you’re not into plastic, Dr. Brown’s makes glass bottles, too.
Real Parent Reviews
“The only bottles that help my [baby’s] colic. Bought them in 2016, and still have them in 2023! Bought some new ones recently and still love them. Hate cleaning them though!” — Abbey
“The best bottle ever for newborn! I tried others & they led to gas, switching to these has been amazing and has made bottle feeding so much easier and more comfortable for my little one!” — Lovedreams23
“I love these bottles for avoiding a colicky baby, wonderful. I haven’t had any issue with colic so far, however, they leak if they aren’t standing upright. They’ve leaked in my diaper bag, they’ve leaked in my pocket. How in the world can you have a leaky baby bottle? That is enough to make me give a low rating. It’s sad because they’re great bottles but the fact that they leak is extremely annoying.” — B8923

Best Baby Bottle for Baby Registry
Pros:
- Lets you try 5 popular baby bottles before committing
- Includes plastic & silicone options
Cons:
- No glass options (Babylist Glass Bottle Box sold separately)
- Can’t select nipple size
Featuring five of the most popular bottles, the Bottle Box lets baby (and you) try out a variety of bottle shapes and styles before committing to a particular brand, solving the all-too-common issue of registering for a whole set of bottles only to realize your baby won’t take them.
“Babies can be opinionated creatures,” Dr. Fradin, a pediatrician, says. And while she assures new parents that this “isn’t worth pre-worrying about” too much, we hear the same sentiment from many new parents—which is why the Bottle Box is so genius and why I think every parent-to-be should add one to their baby registry.
“Babies are unpredictable,” says one Best Baby Products respondent. “The Bottle Box allows you to try multiple brands/types of the product…[because] you’ll have no idea what your baby will like.” Another parent told us how happy they were that they decided to register for the box despite being unsure at first. “I had no idea these were going to come in handy when my youngest wouldn’t take the bottle,” she said.
You won’t be able to customize your nipple size with this sampler pack—all bottles come with level one slow-flow nipples. And there’s no glass option included. But you can try the Glass Bottle Box if you prefer to give glass baby bottles a go over plastic.
Real Parent Reviews
“Great concept for a first-time mom like myself who has no idea what to buy. There are so many options out there and it’s tough to go based on reviews since every baby is different. I loved this bottle pack, and just 2 weeks in I know which ones work best for my family. I would recommend this to any first-time mom. Give this a try!!!!” — Rachel L.
“It is a great way to try a variety of bottles since babies will usually choose the one they want and refuse the rest.” — Shari
“Just a quick warning against this box if you’re a brand new parent — twice I found myself hysterically crying over the sink trying to match nipples and bottles and lids. Y’all, there’s 5 completely different bottles in here and it was HARD. In the first days of parenting when you have no idea what you’re doing, this was a puzzle my brain didn’t have space for. We had to come up with an elaborate ordering system for drying so we could put them back together easily. That being said, found some favorites from here but definitely shed a lot of tears in the thick of it.” — Lindsay G.

Best Bottle for Breastfed Babies
Pros:
- Recommended by lactation consultants
- Nipple designed to mimic the real thing
- Helps reduce gas & colic
Cons:
- Doesn’t include sealing discs (storage caps)
- Flow may be too fast for younger babies (slow flow nipples sold separately)
When choosing a bottle for a breastfed baby, lactation experts recommend focusing on the shape of the nipple. “A tapered shape helps get more of the bottle into the baby’s mouth and promotes a deeper latch,” similar to what baby experiences on the breast, says Spaeth. She, along with other lactation experts we’ve spoken to, all recommend the Lansinoh bottle as a top pick.
With over 50 years of research behind it, the Lansinoh bottle’s NaturalWave nipple is ergonomically designed to mimic a breast, allowing baby to use the same sucking motion so they’ll be able to transition easily between breast and bottle. There’s a venting system to reduce air intake and a vertical groove on the nipple to prevent collapse. And there are only four pieces and no tiny parts, so cleaning won’t take forever, a feature most tired parents (myself included) appreciate.
These eight-ounce bottles come with medium-flow nipples, which many parents say are too fast for younger babies. The Lansinoh Five Ounce Bottles come with slow-flow nipples, or you can purchase the nipples separately.
Real Parent Reviews
“We love our Lansinoh bottles. We exclusively breastfeed and have bottle-fed about 1 bottle a day since my milk came in…Our son has had no trouble going from bottle to breast. Pros: no nipple confusion, easy to clean parts, no leaking, it’s easy to see teat through bottle and baby’s mouth on the teat to assure for a successful feed…Cons: my only con is the bottles don’t fit perfectly with the spectra pump. Despite that we have no cons to share.” — Rebecca
“I received several bottles. These felt less bulky. My son had to see a specialist as a newborn. He had all 4 mouth ties and latching was difficult. They were about to pull out their bottle recommendation when they saw mine and said these are the best for breastfed babies and pulled out the same bottle…I would recommend these.” — Thomas23
“These are really great for breastfed babies. The nipple is soft and pliable. Easy for baby to latch on. The cap is easy to take off with one hand. Affordable. Just a great brand overall. This was the only bottle that my son would feed from other than my breast.” — Latoyaw12

Best Baby Bottle for Newborns
Pros:
- Adaptive flow nipples let baby control the flow of milk
- Innovative nipple shape and placement minimize bottle rejection
- Reduces air intake
Cons:
- Pricey
- Four parts to clean
- Heating milk or formula in the bottle is tricky
- Collapsing silicone insert makes it tough to determine amount consumed
Designed and made in Spain, I was introduced to this bottle earlier this year and was impressed from the start. I was even more impressed after Brittney, a member of the Babylist team, took it for a test drive with her new baby—and raved about it.
“I wasn’t expecting to like it so much,” she said. “I’ve never had problems with bottles in the past, but now comparing it to my experience with the Suavinex, I realized how much milk would dribble out of my son’s mouth and how he had significantly more burps or spit-ups. Even my nanny noticed a big difference and specifically requested to use these bottles.”
There are two things about the Suavinex bottles that make them stand out from the crowd and especially good for newborns just beginning to drink from a bottle. The first is the nipple. It’s available in a range of skin-tone hues and is off-center, which Brittney immediately noticed was “similar to what it would be like if he were nursing.” It’s also adjustable flow, which means no matter the angle (even upside-down), milk flows only when baby is sucking. This mimics breastfeeding and allows baby to control the flow of milk, making for a more consistent feed.
The second is the silicone bag inside the bottle that holds the milk or formula. It collapses as baby sucks, which reduces air intake and can help with gas, fussiness or colic. “The silicone insert allows no bubbles,” Brittney told me. “I legit didn’t see any!” Just note that the insert can make it tough to tell how many ounces your baby drank.
The two biggest downsides of these bottles are ease of cleaning (it can take some time because of the numerous parts) and bottle shape (the wide base doesn’t fit in all bottle warmers). There’s also the semi-hollow base to consider when warming. “My warmer couldn’t accurately heat it up to the appropriate temperature,” said Brittney. And ease of use can be a challenge for some caregivers. “My nanny is at the age of a grandparent, and it took her a while to understand how the silicone insert worked and to correctly face the nipple,” Brittney told us. “I had to walk her through it several times. Eventually, she got it and now she loves it.”
Real Parent Reviews
“We tried a few bottles (Phillips, Medela, Chicco…). Some had too much flow, some were not comfortable for the kid, some made him swallow a lot of air. This one is perfect flow, no extra air and the kid adapted after one session. We could not breastfeed, but this has been really helpful for him to workout suction strength and to avoid colic.” — Daniel
“Excellent teat and very slow flow, so comfortable in mixed breastfeeding for the first few days. The significant flaw is that the plastic of the external bottle is not very transparent, combined with the internal anti-colic bag, it makes reading how much milk is in the bottle really difficult, especially at night when I don’t light up the rooms during the day it’s really difficult. Moral: I use it less and less, preferring other models that are always anti-colic and slow-flowing but that [I can] read.” — Giada_Marco (Translated from Italian.)
“This bottle literally saved me! My 6-month-old daughter who is exclusively breastfeeding refused all bottles, I was totally desperate because I have to go back to work. But I was advised [to try] this bottle and miraculously she accepted it without problems! I am absolutely thrilled. The only downside is that it’s a real hassle to clean it but otherwise it deserves 5 stars.” — Saudemot (Translated from French.)

Best Value Baby Bottle
Pros:
- Great value (<$1.60 per bottle!)
- Lightweight and narrow for tiny hands
- Long, narrow nipple promotes deep latch (also works with Dr. Brown’s nipples)
Cons:
- No anti-colic vents
- Measurements are tough to read
- Can leak easily
The most affordable bottles on our best-of list by far, these Evenflo Feeding Classic baby bottles are an incredible value, especially considering their features and the overwhelmingly positive reviews from parents.
The most affordable bottles on our best-of list by far, these Evenflo Feeding Classic baby bottles are an incredible value, especially considering their features and the overwhelmingly positive reviews from parents.
They check almost all of the boxes for what we like in a baby bottle. The narrow shape, light weight and twisted surface design make them easy and comfortable for baby to hold. Lactation consultants love the nipple shape—it’s gently sloped, which can help encourage a deep latch. They come in multiple colors, a nice-to-have if you’re using bottles with more than one child. And they’re also super easy to clean, with only three pieces.
They do lack a venting system, which may or may not be an issue depending on your baby. And a universal complaint is that the measurements can be tough to see. But considering the price, we still recommend them.

“My picky daughter loves these bottles. They’re lightweight and simple [to] set up compared to other brands. Only would wish for better measuring labels as you have to be in good lighting and align with bottle to see what is poured.” — BBSJ
“I like these bottles because they are BPA free, easy to use but most of all, they’re colorful! You can remember who’s bottle is who’s if you have more than one child. These do not leak, break or deteriorate in any way. Very good product, I have many of these bottles that I use for my 4-month-old son. Great quality bottles.” — AJsMom14

Best Silicone Baby Bottle
Pros:
- Made of durable food-grade silicone
- No small parts to clean
- Inner pouch minimizes gas & colic
- Transitions to sippy cup
Cons:
- Don’t fit in all bottle warmers
- Pouch can refill with air if baby takes long breaks during feeding
- Some parents complained of slight leaks
Silicone bottles are softer and squishier than plastic or glass options. Many parents choose them because they can be easier for baby to hold, feel more like a breast and are free of some of the chemicals plastic bottles contain. Boon’s Nursh bottles are our top silicone pick. Their colorways can’t be beat (so fun!), but more importantly, they’re straightforward to use and can help tiny tummies.
Like the Suavinex bottles, Boon Nursh bottles tackle the concept of a venting system with a silicone pouch that collapses as baby drinks. This results in less air in baby’s tummy, which can help reduce gas, colic and overall fussiness. It also eliminates tiny parts to clean, a nice perk. And unlike some silicone options, these bottles have a sturdy base, preventing any tip-overs.
And because I’m always a fan of any multi-use baby product, these bottles get extra credit in my book for their ability to transform into sippy cups with the easy addition of a straw conversion top, extending their useful life for years. “I originally bought the Boon Nursh bottles because I loved the look (don’t judge me!) and because they seemed really easy to clean (we are dishwasher parents),” Maddie, a Babylist team member, told me. “But I ended up loving them because of the way they transition from bottle to sippy to straw cup. We bought the straw cup attachments when our kid was ready to transition away from bottles, so we’ve been using our Nursh system for over two years now and they are still in great shape.”
Dont-love-it aspects of the Nursh include their awkward fit in certain bottle warmers and that some parents say that if the baby breaks the latch on the bottle, air will flow back into the collapsible pouch—but that wasn’t the case in our testing.
Real Parent Reviews
“I switched to these at around 6 months because the bottles I was using leaked everywhere. I love these! The silicone collapses as baby drinks so there’s no air (which means less spit up and less gas), the nipple is nice and wide, and it’s sturdy so there’s no nipple collapse, the neck is the same width as the rest of the bottle so it’s SUPER easy to clean, and the sturdy case makes it tip-proof and super cute. I will be buying more! Highly recommend!” — Kate S.
“We love these bottles! My baby has only ever used Boon bottles and took to them right away. For me, the beautiful colors make middle-of-the-night feedings more pleasant. The wide neck design makes these bottles easy to clean (especially with the Boon Cacti Cleaning Brush Set). We appreciate that they are lightweight and easy to pack around. The silicone pouches and nipples are durable and nipples are available in 0-3 sizes (extra slow flow to extra fast flow) for babies of different ages. There are also sippy cup lids available to convert the bottles into sippy cups.” — Erynn P.
“These bottles are great at helping prevent gas because the pouch collapses to keep air from refilling the bottle. They are easy to clean and so much easier for my daughter to hold onto. I like how there aren’t ridges on the inside of the nipple which makes it easier to get milk cleaned off them. They are quality-made bottles. The only downside I found is they do leak slightly more than other bottles.” — Reddogmom

Best Glass Baby Bottle
Pros:
- Pharmaceutical-grade glass (heat and thermal shock resistant)
- Included silicone sleeve improves grip and reduces risk of breaking
- Adjustable-flow nipples + anti-colic venting system
Cons:
- Heavy
- Breakable
- Included nipples (sizes 1 and 2) are meant for newborns and may not work well for older babies
Glass baby bottles are having a moment. About a third of the parents we surveyed in our Best Baby Products poll told us they use glass bottles to feed their babies, calling out their durability and that they’re free of the chemicals used in plastic bottles.
These bottles from Philips Avent have all of the components parents love about the brand’s plastic bottles—a wide, flexible nipple, an advanced anti-colic system and few parts to clean—in glass instead. The glass is thermal-shock resistant, so it can transition between hot and cold without issue, and the twin-valve design reduces colic and discomfort by venting air into the bottle, not your little one’s stomach. They’re also ultra durable. “Since they’re glass I was able to save them from baby to baby…without concern of the plastic being too old,” one mom told us in our Best Baby Products survey.
Like all glass bottles, these are heavy, and there’s always a risk of breakage if dropped (the silicone sleeve will help protect from this, though). This set includes five glass bottles (three four-ounce and two eight-ounce) and two silicone bottle sleeves.
Real Parent Reviews
“My husband and I looked for plastic alternative bottles. These bottles are perfect. Our daughter loves them, it is easy to upgrade nipples, easy to read the markers, and they warm up quickly. We also like the glass as opposed to the silicone since the silicone nipples tend to collapse.” — Angelina
“We love the peace of mind that comes with using glass. We used these four years ago with our first son and will be using them again. You can even purchase disks to use in place of the nipple which works great for storing/transporting milk. Post-weaning, we used the sealing disks to store homemade baby food in these bottles. I’ve read reviews from other users about the nipple leaking. This happens when the nipple is not assembled correctly. There are a few YouTube videos that explain how to place the nipple into the piece that screws onto the bottle to solve this problem.” — Jessie O.
“Love Avent and their products! I bought these as a first-time mom because I was thinking glass would be nicer than plastic. Double think it for your needs. I find glass is heavy and gets annoying to hold on little ones and have since switched to the Avent plastic ones! Just something to think about!” — Sara L.

Most Innovative Baby Bottle
Pros:
- Made from Tritan, a durable plastic as clear as glass and free from most toxins
- RealFeel nipples reduce bottle rejection
- Transitions to a straw cup (attachment included)
Cons:
- Pricey
- Only includes 1 straw attachment
- Can’t sterilize with a steam sterilizer
Quark is another new addition to this year’s best-of bottles list. I personally tested the bundle and sent it to an IBCLC friend to try with her new baby, and immediately after trying it,I knew it deserved a spot in our guide. The bottle system is inventive, beautifully designed and—most importantly—makes feeding your baby a little easier.
The most innovative thing about Quark bottles—and likely the first thing you’ll notice—is the material. Made from an engineered plastic called Tritan, the material is lightweight, resists cracking and breaking and is extremely durable. It doesn’t leach harmful chemicals. And it’s also crystal clear; if you looked but didn’t touch, you’d think it was glass. (I’ve been using mine for months and it’s still as clear as the day I took it out of the box.)
The nipple is another exceptional feature. The gentle slope—the nipple shape lactation experts recommend—was the first thing my IBCLC friend, Rebekah, noticed when she saw the bottle. It flexes like the real thing and has two texture zones to replicate the nipple and areola. It was also one of only two bottles her newborn would take. “This baby has thrown me for a loop and refused all pacis from birth, so I was curious how bottles would go,” she said. “I tried a bunch, and Quark and Dr. Brown’s with the preemie nipple were the only two she took well. She got a great latch.”
Like Boon Nursh, Quark bottles will stick around longer than your average baby bottle. Just pop off the nipple and add the straw top insert instead (the conversion set comes with this bundle) to use the bottle as a straw cup for years.
Note: you won’t be able to sterilize these bottles using a steam sterilizer, as the brand recommends against this method. (A dishwasher or boiling the bottles is fine, though.) And they’re expensive—the price breaks down to about $20 per bottle.
Real Parent Reviews
“These bottles are beautiful in their design and functionality. The top snaps on easily and tightly. It won’t come off unless you intentionally take it off, and in that case it comes off easily and quickly. The size and shape of these bottles make it perfect for an older baby or toddler to hold…The most important thing—the nipple—is shaped as nature intended with good pliability. The various sizes of nipples included are such a great idea and just one of the many details about this brand that shows they really have an outstanding product…A major feature of this bottle is that it is made with Tritan…It’s as clear as a crystal, exceptionally durable, shatterproof, and lighter than glass.” — Everly M.
“These bottles are really nice, don’t get me wrong. The plastic is high quality and they feel like better quality than the ones you buy at Target, Walmart, etc. However, I think it is overpriced ($80 at time of posting) for what you get. That is basically $20/bottle. I do like that they grow with your child and can transition into a sippy lid. Anti-colic feature is also nice. Free from many toxins. Overall ,they are great and my baby likes them.” — Leah M.

How We Chose the Best Baby Bottles
We analyzed results from Babylist’s Best Baby Products survey, which polled 6,000 Babylist users and asked them to share the baby products they love the most and why.
We utilized insight from the Babylist editorial team, including me, Gear Editor Jen LaBracio, an expert in the baby space for over six years and a mom of two who has written hundreds of baby gear guides and personally researched and tested hundreds of baby products, including many different types of baby bottles.
We interviewed two experts: Emily Spaeth, an IBCLC and a physical therapist and founder of Be Well Baby PDX, and Kelly Fradin, MD, a pediatrician, writer and New York City-based public health advocate.
We read customer reviews from hundreds of Babylist users and spoke to parents on our Babylist staff about their real-life product experiences.
Baby Bottles: What You Need to Know
Regardless of how you feed your baby, most families use baby bottles at some point. You’ll need to use a bottle if you feed your baby formula or expressed breast milk, or if you plan to return to work within your baby’s first year or be away from your little one for an extended time.
When do you need baby bottles?
You can start using bottles from day one. Babies usually use bottles until at least one year old, which is when the American Academy of Pediatrics (AAP) says it’s okay to transition your little one from breast milk or formula over to cow’s milk. However, many breastfeeding parents continue to nurse well into the second year and beyond.
How to introduce a bottle to a breastfed baby
Introducing a bottle to your baby may look a bit different if you’re also breastfeeding. Many lactation experts recommend waiting until baby has gotten the hang of nursing, usually between about three and six weeks, before you introduce a bottle. And because milk production works on supply and demand, it’s also important to consider how using a bottle will affect your supply.
“If you're breastfeeding, using a bottle, whether of pumped milk or formula, interrupts the supply-demand cycle of a baby sucking the breast to help bring in your milk,” explains Dr. Fradin. “This matters most in the first four to six weeks of breastfeeding, though of course this must be balanced against what's best for the [nursing parent], as skipping feeds to recover from childbirth, to sleep or to function for other life goals is a very valid and often necessary choice,” she says.
She also cautions to not wait too long before introducing a bottle to a breastfed baby. “Around four months, babies can be very distracted during feeds, and parents often find it necessary to feed them in a dark quiet room to get a full feeding in,” she says. “Introducing a bottle during that time or in the weeks around when a parent returns from maternity leave can be pretty stressful.”
How many bottles do I need?
Most parents have six to 12 baby bottles on hand if you’re exclusively bottle feeding. This allows you to have a bottle ready to go whenever you need one (pro tip: hungry babies don’t like to be kept waiting) while you’re washing the others.
If you’ll be using bottles occasionally, three to four is a good number to have on hand.
Types of baby bottles
Bottles are typically made from one of three materials: glass, plastic or silicone.
Glass baby bottles were the norm in the decades before plastic and have recently returned to popularity. While it may sound like a head-scratcher to give your baby something made of glass, glass baby bottles are made from tempered glass, a type of glass that’s extra durable and can withstand being banged around and even dropped.
Plastic baby bottles are made out of polypropylene, a hard type of plastic. Plastic bottles are the most common type of baby bottle on the market and the most affordable.
Silicone bottles are the newest type of baby bottles. They’re made from silicone, a soft, flexible material free from chemicals like BPA, PVC and Phthalate.
Types of baby bottle nipples
Baby bottle nipples come in different sizes. Each provides a different rate of milk flow.
Newborn and slow-flow nipples (sometimes also labeled as level zero or level one nipples) are designed for newborns and younger babies. They provide a slower flow of milk or formula so baby won’t gulp too much too fast.
Faster-flow nipples (levels two and up) are designed for older babies who have bigger swallows and have better control over a faster flow of liquid.
Baby bottle sizes
Most bottles come in two sizes:
Smaller-sized bottles, usually around four ounces, are geared toward newborns who eat less per feeding than older babies.
Larger bottles, which hold about eight ounces of breast milk or formula, are for older babies who eat more.
As a benchmark, newborns may eat as little as an ounce or two every meal. "Most babies aren’t going to need that full eight ounces until they're much older, usually around eight months," says Spaeth. Some parents choose to buy a few smaller and larger bottles, while others buy larger bottles from the start and only fill them up about halfway during baby’s first few months.
How to Choose the Best Baby Bottle For Your Baby
There are pros and cons to every type of baby bottle on the market (and there are a lot of them!). Baby bottles are also highly subjective; what works for one baby or parent won’t necessarily work for another. It can be exhausting to compare every minor detail, so here are some basics to keep in mind when deciding what type of bottles to add to your baby registry.
Glass, plastic or silicone? Compare the pros and cons.
Glass bottles:
Pros: Glass bottles don’t absorb colors or odors like silicone and plastic bottles can. Glass baby bottles are thermal-shock resistant, so they can go from freezing cold to piping hot without breaking. Glass bottles can go right into the dishwasher without the fear of chemical leaching and they’re often easier to clean than other types of bottles because they have fewer parts.
Cons: Glass bottles are heavy. They’re trickier for you (and your baby) to hold, and although it’s not easy to break them, it’s certainly not impossible, either. Glass bottles also tend to be more expensive than other bottle types and there are fewer options to choose from since they’re not as ubiquitous as plastic baby bottles.
Plastic bottles:
Pros: There are tons of options to choose from if you’re registering for plastic bottles, and plastic bottles are also the most affordable type of bottles on the market. Plastic bottles are lightweight, won’t break when dropped and are easy for you and your baby to hold.
Cons: The initial concern over plastic baby bottles was because of bisphenol A, commonly called BPA, an industrial chemical used to make certain plastic that may cause negative health effects. The FDA banned BPA from all sippy cups and baby bottles in 2012, but according to the AAP, the jury’s still out on health and safety concerns around plastics, especially in children and particularly when heated. If you decide to use plastic baby bottles, avoid microwaving them (and avoid microwaving all bottles of milk so you don’t create hot spots) and hand-wash dirty bottles instead of putting them in the dishwasher. Many plastic bottles also have a lot of small parts and can be a hassle to clean.
Silicone bottles:
Pros: Silicone bottles are soft and squishy and most closely resemble a breast; this also makes them easy for you and for your baby to hold. They’re unbreakable and free of many chemicals in plastic bottles. Silicone bottles are dishwasher safe and most contain fewer parts than plastic bottles so they’re easier to clean.
Cons: Silicone bottles are some of the most expensive and there aren’t many options. And although they don’t contain the same chemicals as plastic bottles, there’s still some concern over leaching at very high temperatures. They can also discolor and absorb odors over time.
Look at the nipple
Spaeth tells parents to pay attention to two things when considering a bottle nipple: flow rate and shape.
“Always start with the slowest flow rate nipple,” she advises. A too-fast flow of milk or formula can overwhelm babies, especially newborns. A slow-flow nipple can help pace the feeding session.
“Another big thing to pay attention to is the nipple’s shape,” she says. She recommends a nipple with a gently tapered shape which helps “get more of the bottle into the baby’s mouth and promote a deeper latch.” And look at your baby’s mouth anatomy. “Some nipples are too long and trigger a gag reflex in certain babies,” she explains.
Worried about nipple confusion if you’re switching between the breast and bottle? Don’t be. “Some people have claimed that nipple confusion can occur when a breastfed baby imprints on a bottle or pacifier and no longer knows how to suck on a breast,” says Dr. Fradin. “I am not sure that's the case, but I do think the flow of breast milk can be very different from a bottle. Breast milk requires more work from the baby and is a more dynamic flow whereas a bottle can be more passive and predictable,” she explains.
Pay attention to flow rate
It’s important to distinguish a bottle’s size from its flow rate, says Spaeth. “A larger capacity bottle is just based on how much your baby's eating,” she explains. “The flow rate is what really matters.” Here are a few ways she says you can determine the correct nipple flow rate.
You need a faster flow nipple if baby is:
Taking longer than a half hour to feed. “If they're taking more than 30 minutes to finish a bottle, you should move up.”
Popping on and off of the bottle and seems frustrated.
Compressing the nipple, which creates a vacuum and means they're having to suck too hard to remove the milk.
You need a slower flow nipple if you notice:
Baby is finishing their bottle quickly "The sweet spot is [typically] between five to 25 minutes," Spaeth says.
They're choking, sputtering or leaking milk out of their mouth.
Have red or watery eyes or furrowed brows.
Are popping on and off of the bottle.
Clicking. “Sometimes babies will click and that's them trying to slow the flow," says Spaeth.
And don’t forget…
Here are a few more things to think about as you shop for a baby bottle:
Is the bottle easy to assemble and disassemble?
Is the bottle’s base stable? How likely is the bottle to tip over when full?
How easy is the bottle to wash? How many parts are there?
You’ll also want to keep in mind that babies can be pretty particular about what type of bottle they like best. Since it’s tough to anticipate what your little one will like (or not), we recommend adding either one brand’s starter kit or a sample box to your registry before going all-in on any particular brand.
