Best Overall Baby Bottle
The Comotomo bottle impresses with its eco-friendly silicone, breastlike nipple, and overall simplicity. It offers uncomplicated assembly with only three parts, and the silicone body and nipple ensure that the formula/milk has minimal contact with plastic. The silicone also provides a soft, breastlike surface for babies to grasp when feeding. The nipple is softer than average and has a vent on either side to help your baby swallow less air with each swallow. This silicone is durable, and thanks to its wide-neck design, cleaning is simple even without a bottle brush. However, you'll likely want a small brush to ensure that the nipple valves are clear of residue to keep the milk flowing freely and prevent the growth of bacteria.
We like the advantages of silicone over plastic for the body, but there are some downsides. The pliable structure doesn't create a stiff bottle body, and because the bottle's base is much narrower than the top, it can tip over. Also, silicone's soft and squeezable nature may spray a small stream of milk from the nipple when slight pressure is applied. These are relatively minor drawbacks, which is why the Comotomo is one of our favorites and one we would use or recommend to a friend.

Best Budget-Friendly Bottle
NUK Simply Natural Glass
The NUK Simply Natural Glass is a top-scoring glass bottle with a below-average price tag. The borosilicate glass is relatively durable, and the simple design of the bottle makes it easy to use, fill, and clean. One of the best parts about this bottle is the nipple. It is very soft silicone, has a unique flattened tip and a wide nipple mound, all of which make it one of the most breastlike nipples we've encountered. This nipple is ideal for babies who regularly switch back and forth between bottle and breast.
Unfortunately, glass bottles are more likely to break if bumped or dropped, and NUK does not offer a protective sleeve. While we love the nipple, the very things that make it easy for a baby to latch onto require a bit more attentiveness from the caregiver. You must properly position the asymmetrical shape in the mouth, or it may feel awkward for the infant. Likewise, the nipple vent should be placed directly under the baby's nose; otherwise, it will not correctly release pressure. However, it is easy to work around these peculiarities with extra care, and our testers loved using the NUK Simply Natural.

Best Bang for Your Buck
Evenflo Vented + Glass
Evenflo Vented + Glass bottles are tempered glass that is not as strong as borosilicate but still somewhat resistant to bumps and temperature changes thanks to special chemical treatment. We love that Evenflo offers a bottle that has a price on par with budget plastic bottles while still being made with eco-friendly materials. We did not have any problems with this bottle leaking during testing, and the nipple is soft enough that most babies can latch right on. This bottle is easy to assemble and clean with only three parts, although the small vent on the bottom of the nipple may require a tiny brush to properly clean.
While we love plastic alternatives, you will have to take extra care with these bottles. Evenflo does not offer a protective sleeve, and tempered glass is one of the least durable materials we encountered. The narrow nipple base is less breast-like, and breastfed babies may have more difficulty with this style. The narrow neck opening also makes it a bit more challenging to clean and fill, and you will need to purchase a special bottle brush. However, compared to similarly priced bottles, it is hard to find one with this many perks. If you are on a tight budget but want a glass bottle for health or eco reasons, Evenflo is your best bet.

Best Innovative Design
The Boon Nursh is a bottle with a silicone drop-in liner and a plastic shell. This ventless design is the only one of its kind in our review, and we are impressed with its performance. The wide neck opening is easy to fill and creates a large base for the wide nipple mound. The silicone liner is flexible enough to be turned inside out and cleaned with a regular sponge, although we still recommend using a small brush to reach the inside of the nipple. One of the perks of having a solid plastic shell is that it creates an excellent level of stability that isn't typical of silicone bottles.
The nipple is a bit stiff for our liking. We think this stiffness prevents nipple collapse, as the venting method relies on a vacuum that prevents any air from entering the bottle. The volume markings are numbers found on the plastic outer and correspond with stipes on the silicone liner; even in a brightly lit room, these markings are difficult to distinguish and even more difficult in a dim nursery. Aside from this drawback, we think the Boon Nursh is an excellent option if your baby likes the nipple. Earning top marks in almost every metric, we loved using the Nursh.

Analysis and Test Results
With so many baby bottles to choose from, it may be hard to tell the difference between manufacturers' features and claims to be the "best." Honestly, it may be tempting to close your eyes, point your finger, and let fate decide. However, we think some specific qualities can make your baby bottle days much easier or more complex, depending on your choice. We suggest pre-determining how you plan to feed your baby and what features are important to you before investing in a bottle for your little one.
When purchasing a baby bottle, you should consider how much you plan to use it. Are you planning to bottle-feed exclusively? If so, you will want a durable bottle that stands the test of time. Suppose you plan to breastfeed and occasionally supplement your baby's diet with formula, then a bottle's functionality may be less critical. Another consideration is the cost of healthier materials. A plastic bottle, like the Tommee Tippee, is a lightweight and economical option with a well-liked nipple with an easy to use and clean design. However, the lower price of plastic may not be as high a priority to you as the value of using healthier materials like silicone. If so, we think the Comotmo is a great value that is easy to use and should last for the duration of your baby's bottle-feeding years, making it a good value for longevity.
The last thing you want to worry about is leaking. Plus, when hunger hits, you will want to whip up a bottle, screw on the top, and soothe your hungry baby ASAP. During testing, none of the bottles leaked when correctly assembled. In our opinion, bottles with fewer parts, such as the Evenflo Vented + Glass or the Comotomo, are less likely to be assembled incorrectly, which can prevent leaks. Our tests show that when used in conjunction with the aLoo, any bottle may leak if left on its side too long.
Top performers in this metric are the Comotomo and Nuk Simply Natural, both earning 9's. You are more likely to experience leaks from a poor latch than from the cap of these bottles.
It can be challenging to know which nipple type your baby will prefer. We recommend narrowing down the options to a few brands and purchasing one bottle from each to test for the first few weeks. Almost all nipples are silicone and vary in shape. Also, some are stiffer, whereas others are softer. However, there are a few common characteristics that babies typically like. In general, the more breast-like the nipple is, the more likely the baby is to get a good latch. A nipple with a broad base is usually best. Most manufacturers offer various flow rates, and selecting the correct one for your baby's age is a must. The NUK Simply Natural Glass has a flattened nipple tip and soft silicone, which closely imitates the breast.
Every baby bottle in this review has an anti-colic system or claim. Most of the competition uses a vented nipple, which allows a small amount of air to pass through a hole in the nipple base to prevent a vacuum. The Lifefactory has ridges on the base of the nipple that serve the same purpose.
Others have an additional component that allows air in and out of the bottle. The Joovy Boob Diamond has a collar that fits around the bottle's rim and leaves a bit of space without releasing milk. Dr. Brown's is perhaps the most complicated anti-colic venting system using multiple parts that require special cleaning tools. However, parents of colicky babies often swear by this bottle.
Last, as seen in the Boon Nursh, having no vent can also be an effective anti-colic system. This bottle features a silicone liner that seals tightly with the nipple and creates a vacuum. As your baby drinks, the liner collapses to relieve the pressure without the need for added air.
Ease of Cleaning
All of the bottles in our roundup claim to be "dishwasher safe" by the manufacturer. However, as a general rule, we strongly recommend handwashing plastic parts to reduce leaching chemicals' potential and prolong a product's life.
We recommend using a bottle brush for handwashing all things bottle or sippy-related. But, even with a special brush, some parts can be more challenging to clean than others. A baby bottle with a narrow mouth opening can spray as you pull the brush out, but wide-neck options are less likely to create a messy spray. The Boon Nursh has only two parts that need actual scrubbing, both of which can be turned inside out and cleaned with a regular sponge.
Eco-health is very important to us. Keeping this in mind, most of the bottles we tested are glass or silicone, which are generally considered safer for babies and the environment than plastic.
There are three main types of plastic used in bottles: Polypropylene (PP), Polyethersulphone (PES), and polyphenylsulfone (PPSU).
- PP plastic is the cheapest and least durable of the three types. It can quickly degrade in boiling water and can only withstand max temperatures up to 120° C. If you have a bottle that uses this plastic, experts recommend replacing it every six months.
- PES is the middle-of-the-road option. It will start to degrade when placed in boiling water and can handle temps up to 180° C, making it more durable for daily use. Experts recommend that you change PES bottles every six months as well.
- PPSU is the highest performing, most notably for durability and heat tolerance. It is frequently used in aerospace and medical devices. You can repeatedly sterilize it in boiling water thanks to its high melting point of 208° C. It is naturally BPA-free and does not absorb color or odor. Experts recommend you replace PPSU bottles yearly.
If the manufacturer does not state the plastic used in the bottle, we assume it is PP.
When it comes to glass, there are two types to consider: borosilicate glass and tempered glass. Borosilicate glass has an entirely different chemical makeup that is highly durable and helps bottles endure significant and sudden temperature changes without breaking. These bottles generally last a long time and can be trusted to withstand daily use with ease. Tempered glass is created by treating regular glass with a chemical or thermal process to increase durability and lessen the likelihood of breakage from drops and bumps. It is more resistant to heat, but it is still not a good idea to go straight from the freezer to the bottle warmer with tempered.
Silicone is an excellent compromise among the various material options. It is much healthier than plastic, plus more durable and lighter than glass. Silicone bottles used to be a rarity, but today, the market is bursting with new options. Silicone products in our lineup include the Comotomo and the Boon Nursh.
Ease of Use
If you're bottle-feeding, chances are you'll be handling baby bottles upwards of 7 times a day for the first few months. We suggest selecting a product that is effortless to use.
You should ask yourself questions like, how many pieces will I have to assemble and clean? How tricky is a liquid transfer? Is it comfortable to hold? Our favorite bottles have very few parts and are fool-proof to assemble. Bottles such as the Boon Nursh with a wide neck opening will be much easier to mix formula or pour breastmilk into, reducing waste and eliminating the mess. However, like the Evenflo Vented + Glass, narrow neck options can result in liquid loss or mess.
If you want to monitor how much your baby is drinking, we suggest selecting a bottle with distinct volume markings. Also, ask yourself, is it comfortable to hold? What about for your baby? Glass bottles like the Lifefactory or the NUK Simply Natural Glass are heavier and more challenging for a baby to hold. Alternatively, plastic and silicone options are generally lighter and more comfortable for small hands to manage, and the Comotomo is lightweight and pliable for easy gripping.
Your little one could potentially be using a baby bottle multiple times a day for over a year. This reality means selecting the right baby bottle that works for your baby and meets your needs is critical for successful feeding. It helps to consider factors such as leaks, ease of cleaning, and convenience, in your decision-making process. Luckily, we've completed extensive testing to bring you the details you'll require to make an informed decision. While we can't say what features your specific baby may prefer, we feel confident there is something for every baby in our lineup.
