The Best Bottles According to Parents, Experts and Picky Babies
The Best Bottles According to Parents, Experts and Picky Babies

Choosing a baby bottle is a complicated affair. There are a ton of options on the market. 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. And even after all of the consideration, your baby is the ultimate judge!

We tested dozens of bottles in the real world, spoke to lactation experts and a pediatrician and reviewed feedback from thousands of parents. What we found? Bottle preferences are deeply personal—what works wonders for one baby might be a total miss for another. We’ve also noticed an increase in parents’ preference for glass bottles, so we have two best overall picks, whether you’re looking for a plastic option or prefer a glass bottle. Dr. Brown’s Options+ Anti-Colic Bottles are our top plastic bottle pick overall, and for glass, we love the Philips Avent Glass Natural Bottles. Both come highly recommended by real parents and have features that we think will work for most babies. However, because bottles are so subjective, we’re also including a range of standout options, including bottles designed to help with gas and fussiness, silicone picks and breastfeeding-friendly styles. 

Whether you’re just starting your feeding journey or troubleshooting a bottle strike, finding the right fit may take a little trial and error—but we’ve got you covered.

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 annually via our Best Baby Products online survey. We know what items millions of expecting parents are adding to their baby registries.

  • Firsthand and professional experience. As a mom of two, I’ve had the opportunity to test out dozens of bottles during my own feeding journey with both of my children. I’ve also completed 52 hours of training to become a certified lactation counselor (CLC) and used both of these experiences to help choose the bottles on this list. I also utilized insight from Babylist’s 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.

  • Expert POV. I talked to two professionals for their expert insight: Kelly Fradin, MD, a pediatrician, writer and New York City-based public health advocate, and Emily Spaeth, an IBCLC, physical therapist and 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.

  • Baby bottle data. I regularly analyze which baby products our users are adding to their baby registries the most (and which ones they aren’t) and what our team of merchandising experts—our buyers who are responsible for ensuring the Babylist Shop is stocked with the best and newest gear—is excited about. Studying this kind of data helped us choose which bottles to narrow in on and which ones to recommend to new and expecting parents.

  • Feedback and reviews. I reviewed comments and feedback from Babylist’s annual product survey of thousands of parents, read customer reviews from hundreds of Babylist users and spoke to parents on our staff about their real-life product experiences.

How We Judged the Best Bottles

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.
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.
Materials
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.

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

  • Value

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

Just under 40 percent of Babylist parents named Dr. Brown’s as their favorite bottle in our best products survey—more than any other brand. And our gear editor Jen LaBracio is one of them. “I used Dr. Brown’s bottles daily for four years with my two boys, one of whom was a preemie with latching issues,” she says. “They were the only bottles that consistently worked for both of them.”

The brand’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.) Still, enough parents tell us they see a noticeable difference when using Dr. Brown’s that we stand behind them. “My three-week-old has not thrown up once, spit up or had bad gas,” one mom noted in our survey. Dr. Brown’s bottles are “the only ones that worked for my baby for the first six months,” another said.

Lactation consultants also 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. One Babylist parent said in their review, “My daughter is very picky when it comes to her bottle. She doesn’t accept most of the nipples [but] we tried Dr. Brown’s and she was able to latch on from the first try.”

The two biggest negatives of these popular bottles are difficulty in cleaning 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. ”We’ve been using these bottles for three months and they leak so bad. It’s so annoying. Baby is soaked in milk and we can’t tell how many ounces he’s actually eating,” one Babylist parent wrote in their review. The good news is that this 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 our biggest learnings from extensive testing and years of use is to remember to always use the Travel Disc and keep the bottle upright when on the go. You should also loosen the collar just a bit before warming the bottle to reduce the pressure.

The last possible downside? These are completely made of plastic. So if you’re someone who wants to avoid plastics in your baby’s feeding gear, you may want to go with the glass version.

Best Glass Baby Bottle Overall

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 bottles have become much more popular in recent years due to some parents’ preference for plastic-free feeding tools. In fact, a little less than 50% of Babylist parents who responded to our survey said they prefer them over plastic, citing that glass bottles are free of the chemicals used in plastic bottles, durable and easy to clean. And when it comes to favorites, parents told us these bottles from Philips Avent top their list.

They 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—but in glass. 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 survey.

Of the glass bottle options we tested, these are definitely on the heavier side. And though they’re super durable, there’s always a risk of breakage if dropped (the silicone sleeve will help protect from this, though). A few Babylist parents also note in their reviews that these leak. “If you don't close the top just the right way, the bottles will leak out. Even when you think you have tightened the top enough, milk will still leak out,” one shared.

Best for Baby Registry

Babylist Glass Bottle Box.

Pros

  • Lets you try 4 popular baby bottles before committing
  • Includes all glass bottle options

Cons

  • Can’t select nipple size

Since bottles are super subjective, and glass tends to be more expensive than plastic, the Bottle Box is a cost-effective way to try them out before committing. We think most parents-to-be should add one to their baby registry because it solves the all-too-common issue of registering for a whole set of bottles only to realize your baby won’t take them. “The Bottle Box allows you to try multiple brands/types of the product…[because] you’ll have no idea what your baby will like,” one Babylist parent wrote in our survey. The box features brands Dr. Brown’s, Philips Avent, Suavinex and BIBS.  

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.

The biggest downside to this try-it kit is that you won’t be able to customize your nipple sizes—all bottles come with level one slow-flow nipples. If you decide glass bottles actually are not for you, there is also a plastic bottle box version, too. 

Best Bottle for Breastfed Babies

Lansinoh Anti-Colic Baby Bottles - 5 Oz.

Lansinoh Anti-Colic Baby Bottles - 5 Oz

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)
  • Can leak

If you’re planning to breastfeed your baby, you may still find yourself wanting to introduce a bottle for times when you’re away from your baby or just want someone else to help with feeds. 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 for breastfed babies.

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. 

Though there isn’t an elaborate anti-colic venting system, there is a small vent to reduce air intake and a vertical groove on the nipple to prevent collapse. And with only four pieces and no tiny parts, cleaning won’t take forever (a feature most tired parents appreciate).

These five-ounce bottles come with slow-flow nipples, which is perfect for younger babies. The larger eight-ounce size comes with medium-flow nipples, which many parents say are too fast for younger babies. Lansinoh also sells nipples separately (at places like Target and Walmart) if you find you need to experiment with different flow rates. They can also fit Pigeon nipples, our runner-up for switching between breast and bottle.

The biggest gripe parents have with these bottles is the potential for leaks. “It’s unfortunate how much these bottles leaked every time I gave it to my baby…It’s a little awkward when others are trying to give her a bottle with this and their hand is covered with breast milk,” one Babylist parent wrote in their review.

Another Great Option

Pigeon Glass Nursing Bottle

From $35.99
Buy
Buy

Pros

  • Glass
  • Sloped nipple passes the “triangle test”
  • Few parts, easy to clean

Cons

  • Pricey
  • Break easily

It was really hard to choose just one bottle for transitioning from breastfeeding to bottle feeding—each baby is different—but Pigeon is another great choice. Even if a bottle has all of the right characteristics according to lactation professionals, the baby is the ultimate judge. 

These bottles from Japanese brand Pigeon are a favorite among lactation consultants—and for good reason. Like the Lansinoh bottle, Pigeon’s nipple design passes what experts call the “triangle test,” which means the nipple has a wide base, gradual slope and soft tip. This shape encourages a deep latch and helps babies transition between breast and bottle more smoothly.

Another feature both bottles share is simplicity. Pigeon bottles have minimal parts, making them easier to clean and reassemble—something parents quickly find that they appreciate during those middle-of-the-night feeds.

But one key difference is that Pigeon offers their bottle in a glass version, which is why we thought it deserved a callout here. Many parents prefer glass for its durability, ease of cleaning and chemical-free peace of mind. (Lansinoh did offer a glass option in the past, but it’s become increasingly hard to find in stock.) 

The nipple itself comes in five different flow rates, so you’re sure to find something that works for your baby, though the size scale differs from most US brands. One parent struggling with bottle refusal shared in their review, “​​So far these have been the best bottles for my baby who absolutely refuses bottles. It’s a struggle even with these ones, but they are still by far the best so far. She has a posterior tongue tie and had a harder time with latching and would not take a pacifier whatsoever. If you’re struggling with bottle refusal it’s worth it to have these in the lineup.” It also has a latch line guide, which one parent said was “nice as a new mom to know she was getting a deep latch.” The wide-neck design also makes it super easy to clean, and they’re also dishwasher safe.

There are some downsides to these bottles. The first is the cost—they’re definitely not a budget-friendly option, costing around $15 a piece. They’re also currently only available on Amazon or the brand’s website. And while glass bottles are durable, they’re still glass, and a few parents mentioned they broke easily when dropped—though this isn’t typical (more on that below). You should regularly check any type of baby bottles for wear and tear, to ensure they’re safe for baby. If you’re not exclusively sticking to glass bottles, there’s also a plastic version.

Best Affordable Baby Bottle

Evenflo Feeding Classic Clear Plastic Baby Bottles

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

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. “Their price is icing on the cake. After five kids we have tried them all and we always come back to these,” one parent raved in their review. 

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. The nipple shape is gently sloped—and similar in shape to Dr. Brown’s nipples—which can help encourage a deep latch. (Pro tip: Dr. Brown’s narrow nipples also fit this bottle.) 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 also come in a glass version if you want to steer clear of plastic.

There are two things that aren’t so great. These bottles do lack a venting system, which may or may not be an issue, depending on your baby. Some parents mention it makes it hard for their baby to drink from them: “Because these bottles have no venting, the pressure builds up inside the bottle causing the milk to get stopped up.” And a common complaint is that the measurements can be tough to see. One parent attests, “The numbers are pretty much invisible, making it hard to measure.”

Best Silicone Baby Bottle

Boon NURSH Silicone Pouch Bottles - Gray, 4 Oz

From $19.99

Pros

  • Made of durable food-grade silicone
  • No small parts to clean
  • Inner pouch minimizes gas & colic
  • Transitions to sippy cup

Cons

  • Doesn’t fit in all bottle warmers
  • Pouch can refill with air if baby takes long breaks during feeding
  • Some parents complained of slight leaks

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. These 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. 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 Nursh bottle

These bottles also get extra credit 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.”

Aspects of the Nursh that aren’t so great 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. Another common complaint is that they leak. One parent said, "You have to be careful to fit it properly so that there are no leaks. The liquid comes out very easily through the hole and the flow is fast.” It’s also super hard to see the measurements on the side of the bottle (because they blend in with the silicone) if you want to know exactly how many ounces your baby finished.

Most Innovative Baby Bottle

Quark BuubiBottle Hybrid Baby Bottle Bundle - Grey

From $79.99
Buy
Buy

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

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, even after repeated use and washing. While many modern baby bottles made of plastic are BPA-free and rigorously safety-tested, not all plastics offer the same long-term clarity and resistance to clouding or staining. Tritan stands out not just for its safety profile, but also for how glass-like it looks and feels. It’s crystal clear—if you looked but didn’t touch, you’d think it was glass. Even after months of use, our gear editor says they remained nice and clear.

The nipple is another exceptional feature—its gentle slope aligns with the nipple shape lactation experts recommend. 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 that Rebekah—an IBCLC and mom of two—could get her newborn to take. “This baby has thrown me for a loop and refused all pacis from birth, so I was curious how bottles would go,” says. “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.”

Quark Buubibottle

Like Boon Nursh, Quark bottles will last 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.

The biggest complaint about these bottles is that they’re not steam sterilizer safe. If you want to sterilize them, the brand recommends immersing them in boiling water for one to two minutes. And though they’re dishwasher safe, Quark also recommends handwashing for a longer lifespan. (The bottles have a super wide opening which makes this pretty easy.) And lastly, they’re expensive—the price breaks down to about $20 per bottle.

Types of Baby Bottles

When you’re searching for bottles to try, keep in mind that they come in three different materials: glass, plastic and silicone. And each has their own pros and cons.

Bottle group photo: Dr. Brown's Narrow Options+, Lansinoh Baby Bottle, Pigeon Bottle, Evenflo Classic Bottle, Philips Avent Glass Natural Bottle, Boon NURSH bottle, Quark Buubibottle

Glass bottles:

  • Pros: Glass bottles don’t absorb colors or odors the way silicone or plastic bottles can. They’re also thermal-shock resistant, meaning they can go from freezing cold to piping hot without breaking. Many are dishwasher-safe without the risk of chemical leaching, and because they often have fewer parts, they tend to be easier to clean than other types of bottles.

  • 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: Many parents wonder if plastic bottles are safe to use. 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.

How to Choose a Baby Bottle

There’s no perfect bottle—just the one that works best for your baby and your sanity.  “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. 

Nipple Know-How: Choosing the Right Flow and Shape

Spaeth says nipples come in different flow rates and shapes, and both can affect how your baby feeds.

“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.

Lansinoh, Pigeon and Quark sloped bottle nipples

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,” Fradin says.

How do I know it’s time to change nipple flow?

According to Spaeth, flow rate—not just bottle size—is key to feeding success. “A larger capacity bottle is just based on how much your baby's eating,” she explains. “The flow rate is what really matters.”

Here’s how to know if it’s time to adjust:

Signs baby needs a faster flow:

  • Feeds take longer than 30 minutes

  • Baby pops on and off the bottle or looks frustrated

  • Nipple is compressed or flattened during feeding

Signs baby needs a slower flow:

  • Finishes bottles in under five minutes (the ideal range is five to 25 minutes)

  • Coughing, choking or milk dribbling from mouth

  • Red or watery eyes, furrowed brows or clicking sounds while feeding

Other Bottle Features to Consider

Before adding baby bottles to your registry, here are a few more things to consider:

  • Ease of use: Can you quickly assemble and disassemble it?

  • Stability: Does the bottle stand firm when full?

  • Cleaning effort: Fewer parts usually mean easier cleanup.

Baby preferences: Babies can be picky—consider starting with a starter kit or bottle box sampler to test what they like best.

Baby Bottles FAQ: What You Need to Know

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 says it's okay to transition your little one from breast milk or formula over to cow's milk. At that point, babies will still use bottles and begin to transition to a sippy cup.

How do I introduce a bottle to my 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. 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 not to 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.

What are the 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.

What sizes do baby bottles come in?

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.

What size of bottle nipple does my baby need?

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.
