The Comotomo bottle impresses with its eco-friendly silicone, breast-like 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, breast-like surface for babies to grasp when feeding. The nipple is softer than average and has a vent on either side to help your baby ingest less air with each swallow. This silicone is durable, and thanks to its wide-neck design, cleaning this bottle is simple, even without the best baby 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, 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. The Boon Nursh is a similar silicone, but it is less prone to tipping in our tests. Also, silicone's soft and squeezable nature (something babies will likely love) may spray a small stream of milk from the nipple when slight pressure is applied (frankly, just like mom). Despite these relatively minor drawbacks, the Comotomo is one of our favorites, and we would use or recommend it to a friend.

The NUK Simply Natural Glass is a glass bottle that meets our criteria as a top-notch bottle. 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's soft, has a unique flattened tip, and a wide nipple mound, which we believe is more breast-like. This nipple might be good for babies who regularly switch back and forth between bottle and breast.
Glass is more likely to break if it falls or is dropped, and NUK does not offer a protective sleeve like some of the competition (even as an accessory). While we love the nipple, it requires a bit more attentiveness from the caregiver because you must correctly position the asymmetrical shape in the mouth, or it may feel awkward for the infant. Plus, the nipple vent should be placed directly under the baby's nose; otherwise, it can't correctly release pressure. The Evenflo Vented + Glass is also one to consider for gassy or colicky babies, as it is designed to vent excess air. However, the Nuk is easy to work around these peculiarities with extra care, and our testers loved using the NUK Simply Natural. We think this contender is worth considering if you're searching for an outstanding glass baby bottle.

Available Sizes 4, 8 oz Material Tempered Glass Weight 4.9 oz Bottle Mouth Narrow Anti-Colic Feature Vented nipple The
The Evenflo Vented + Glass bottles use 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 priced 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 clean appropriately.
While we love plastic alternatives, you must take extra care with glass bottles. Evenflo does not offer a protective sleeve, and tempered glass is one of the least durable materials we encountered during testing. The narrow nipple base is less breast-like, and breastfed babies may have more difficulty with this style. If a wider nipple mound works better for your little one, the NUK Simply Natural Glass has a wider mound and an adaptable nipple that might be easier for some babies to latch onto. The narrow neck opening in the Evenflo 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.

Available Sizes 4, 8 oz Material Silicone, Plastic Weight 3.2 oz Bottle Mouth Wide Anti-Colic Feature Collapsible silicone pouch The
The Boon Nursh has a unique design, and we are impressed with its performance. It's a ventless system that uses a silicone drop-in pouch that collapses as the baby drinks to reduce gas-producing bubbles that can upset babies' bellies. The wide neck opening makes filling during bottle-making easier, and we consider the wide nipple mound more breast-like. 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.
We appreciate a bottle that provides a boob-like experience for babies, and the hard plastic shell keeps babies from feeling the breast-like, squishy silicone body. Also, the nipple is a bit stiff for our liking. However, we think this stiffness prevents nipple collapse, as the anti-colic method relies on a vacuum that prevents any air from entering the bottle. The Comotomo has a better nipple, in our opinion, though every baby is different. The volume markings on the Boon are on the plastic shell and correspond with stripes on the silicone liner. Even in a brightly lit room, the markings are difficult to distinguish and even more difficult in a dim nursery. However, we loved using the Boon Nursh and think the collapsible liner may work for super burpy babies.

How We Test Baby Bottles
We purchased each product in this review for hands-on testing. Our extensive testing took place in-house at BabyGearLab, which includes side-by-side comparisons to evaluate critical metrics like leakage, ease of cleaning, eco-health, and more to determine the best. Also influencing our final analysis and rank of products is feedback from infant testers and their caregivers who participated in the testing process.
Baby bottles are tested across 5 performance metrics in our review.
- Leakage (30% weighting of overall score)
- Nipple (25% weighting)
- Ease of Cleaning (20% weighting)
- Eco-health (15% weighting)
- Ease of Use (10% weighting)
The bottles each undergo real-world testing with tiny testers, and we combine that feedback with more than 9 in-house tests to influence scoring and awards. Tests include leak testing, including upside down in a diaper bag, nipple feel, pliability, flow, and latch-ability, as well as eco-health research, ease of cleaning, and ease of use.

How to Pick the Best Baby Bottle
Babies can be particular and fussy when it comes to baby bottles. The first thing you should know is it can take some trial and error to find the bottle your baby uses without frustration or refusal. So, give yourself and your baby some grace by first realizing that no matter how much you research or consider, the best option is often up to your little one and can require buying more than one type. We think some specific qualities can make your baby bottle days easy or complex, depending on your choice.
Materials
Perhaps one of the most important considerations, and the quickest way to narrow the options, is to choose what kind of materials you'd like to use. We aren't huge fans of plastic and are drawn to the silicone and glass bottles, However, plastic is less expensive than glass or silicone and glass can be heavy. Only you can determine what is best for your baby and situation based on your budget and goals.
Ease of Use and Cleaning
Because your bottles will be used frequently, it is best if they are easy to assemble, use, and clean. Fewer parts is better, simplicity is key in our opinion. However, if your little one is colicky, you might need a more convoluted bottle. No one wants to waste time with a complicated bottle, so finding a system you can stick with is key.
Buy a Single First
We recommend buying a single version of one or two different models to see what your baby likes best before you buy a multi-pack or specific system. While the bottle you end up not using might be a waste of money, it will save you money, time, and frustration in the long run if your little one hates and refuses to feed (and they do this).
The four parts of the PopYum are all relatively easy to clean, but a bottle brush is necessary for the oddly shaped nipple.The formula gets scooped and stored in the nipple section of the bottle.
Analysis and Test Results
With so many baby bottles to choose from, it may be dizzying to tell the difference between manufacturers' features and claims. We tested things like ease of use, cleaning, leakage, and more to help provide the details to help you determine how you plan to feed your baby and what features are important to you before investing in a bottle for your little one.
Investing in a high-quality bottle may be a good choice depending on your lifestyle.

Value
When purchasing a baby bottle, 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. If you plan to mainly 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 Closer to Nature or Lansinoh, is lightweight and sometimes more affordable, making it one to consider for daycare or while traveling with your baby. However, for some families, the lower price of plastic may not be as high of a priority if you value using eco-healthier materials, like glass or silicone. The Evenflo could be a great everyday bottle that uses glass and is budget-friendly. We also think the Comotomo is a well-rounded option that offers excellent value. It's easy to use and should last the duration of your baby's bottle-feeding years, making it a good value for longevity.
A leaky bottle is the last thing you want to worry about when feeding a baby.

Leakage
The last thing you want to worry about is leaking. Plus, once your baby's hunger strikes, you will want to whip up a bottle, screw on the top, and soothe your hungry baby ASAP. None of the bottles leaked when correctly assembled during testing, so the key to our testing was which bottles could easily be incorrectly assembled. In our opinion, bottles with fewer parts, such as the Evenflo Vented + Glass or the Comotomo, are less likely to trip you up, resulting in fewer leaks.
Top performers in this metric are the Comotomo and Nuk Simply Natural. You are more likely to experience leaks from a poor latch than from the cap of these bottles.
Baby bottle nipples come in all shapes and sizes.

Nipple Type
One nipple type doesn't necessarily work for all babies, and it can be challenging to know which one your baby will prefer. We recommend narrowing the options to a few brands and purchasing one bottle from each to test for a few weeks.
Almost all nipples are silicone and vary in shape. Some are stiffer, whereas others are softer. There are a few common characteristics that babies typically like. In general, the more breast-like the nipple is, the more likely a baby will get a good latch. A nipple with a broad base is usually best. Most manufacturers offer various flow rates, ranging from slow to fast. Selecting the right level for your child can depend on a few factors, such as the child's age and if they're transitioning between breast and bottle, because you will want to select a nipple flow rate with the same effort as breastfeeding to avoid preference. You can locate the nipple's flow rate on the packaging or the nipple itself. The NUK Simply Natural Glass has a flattened nipple tip and soft silicone, which closely imitates the breast.
Check Bottle Nipples
Frequently check the nipple for discoloration, thinning, cracks, or breaks, and replace them if you notice signs of wear and tear.

Anti-Colic Features
Swallowing air during feeds is one of the most common ways for babies to trap gas bubbles in their digestive tract, which can cause discomfort and fussiness. Every baby bottle in our lineup has an anti-colic system or claims to limit the amount of ingested air. The Dr. Brown's Natural Flow Original has a more complex anti-colic vent system using multiple parts, and some parents of colicky babies often swear by this bottle. Other contenders use 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 Glass Bottle has ridges on the nipple's base that serve the same purpose.
The single nipple vent is located on the bottom edge of the nipple and fits just inside the upper rim of the bottle.The nipple on the Comotomo has dual anti-colic vents.The nipple on the Tommee Tippee Closer to Nature has a single anti-colic vent.
Others have an additional component that allows air in and out of the bottle. The Joovy Boob Diamond has a collar that fits the bottle's rim and leaves a bit of space without milk release.

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.
We suggest handwashing all plastic bottles and parts, despite being dishwasher-safe.

Ease of Cleaning
All the bottles in our test group claim to be &#;dishwasher safe&#; by the manufacturer. However, we strongly recommend handwashing, especially for plastic parts, to reduce the potential for chemicals to leach and to prolong the product's life.
The Comotomo and mimijumi are the simplest bottles in the group. These bottles are a cinch to clean with fewer parts and a wide neck opening. Our least favorite bottle to wash is the Dr. Brown's Natural Flow Original. Its anti-colic system has several parts with nooks and crannies, requiring a special brush to thoroughly clean smaller crevices. However, if this bubble-reducing bottle works for your little one, it may be worth the extra effort to avoid baby discomfort and spit-up.
We highly recommend using a top-ranking baby bottle brush for handwashing, and even a special brush, which can help clean smaller 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 can be turned inside out and cleaned with a regular sponge.
The baby bottle competition uses various materials, such as glass, silicone, plastic, or a blend.

Eco-Health
Eco-health is very important to us. Keeping this in mind, most bottles we tested are glass or silicone, which are generally considered safer for babies and the environment than plastic.
Nanoplatics
A recent
&#;the Nebraska team further found that three-quarters of cultured embryonic kidney cells had died after two days of being introduced to those same particles. A report from the World Health Organization recommended limiting exposure to such particles.
For these reasons, we prefer glass over plastic and recommend not microwaving plastic containers.
A recent University of Nebraska study on microwaving plastics showed that when some plastics heated in the microwave can release enormous numbers of plastic particles. In some cases, the levels can reach more than 2 billion nanoplastics and 4 million microplastics for every square centimeter of the container. While the health impact of these kinds of particles is still foggy, a recent article stated For these reasons, we prefer glass over plastic and recommend not microwaving plastic containers.
Plastic baby bottles are widely available, and we understand why they remain popular. Plastic is more affordable, more durable, lightweight, and can be more convenient to use. However, given the potential risk of chemicals leaching and exposure to microplastics, it's not our preferred material for feeding. Therefore, plastic contenders tend to rank low in this metric, especially the PopYum. Not only is the entire bottle made of plastic, but it also has pieces and more plastic mass overall than other bottles.
The PopYum, Tommee Tippee Closer to Nature, and Dr. Brown's Natural Flow Original are some of the plastic bottles we looked at.

Advice on Plastics
Some evidence suggests that high temperatures and shaking from the bottle preparation process can potentially increase and release microplastics into a baby's bottle. Here are some tips when using plastic bottles:
- Warm formula or breast milk in a glass or stainless steel container in a bowl of hot water (not in a microwave) and allow it to cool to room temperature before transferring it to a plastic bottle.
- Let a plastic bottle cool after sterilization, then rinse a few times before adding liquid
- Throw away plastic products that are scratched, cloudy, or damaged. While they might still work, they are potentially putting plastic into your baby's food.
- For extra caution, consider replacing plastics every six months.

Some glass options include the Lifefactory, Joovy Boob Diamond, Evenflo Vented + Glass, and NUK Simply Natural Glass.

Baby bottles that use borosilicate glass rank higher than the competition. 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 typically handle daily usage. The Joovy Boob Diamond and Lifefactory Glass Bottle score highly, as they use this type of glass, create an environment where liquid has little to no contact with plastic, and come with a silicone sleeve for added protection and grip for little hands. We also appreciate that the packaging of the Joovy Boob Diamond mentions that the glass is thermal shock resistant, allowing it to go from freezer to one of the best bottle warmers. The NUK Simply Natural Glass is a close runner-up. While it doesn't offer a silicone sleeve, it uses borosilicate glass.
Comparatively, tempered glass, which is what the Evenflo Vented + Glass uses, 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 glass.
The Comotomo and the Boon Nursh both have bodies made primarily from silicone.

Silicone is an excellent compromise among the material options. It is much healthier than plastic and more durable and lighter than glass. Silicone bottles used to be a rarity, but today, the market is bursting with silicone. Silicone products in our lineup include the Comotomo, Boon Nursh, and Nanobebe Flexy.
Interestingly, the Chicco Duo is a hybrid bottle, unlike any other contender in the lineup. The interior uses a very thin layer of glass called INVINCI-GLASS, which adheres to a plastic exterior. Essentially, it seems to combine the best of both worlds; your baby's milk touches the glass, and the plastic makes it durable and lightweight. Being a newer concept, we began researching this material but ended up sort of empty-handed. Therefore, we had a few questions for Chicco, such as: How do you know if the glass interior experiences breakage or damage? Here's what Chicco shared with us:
"Technology for the Duo bottles is proprietary. They are developed using an advanced patented technology that has been in use in medical and pharmaceutical products&#; The bottles are made in the USA and meet all state and federal regulatory requirements." &#; Chicco
In our opinion, Chicco did not share as much information as we would have hoped or what we think parents deserve. Their answer to our inquiries lacked the kind of details that would have increased our confidence in recommending this new technology. While we aren't saying anything is wrong with it or the hybrid bottle, we are hesitant, given the vagueness. In addition, we discovered evidence from other users of bottle rims melting during the sterilization process and concerns about potentially broken glass going undetected inside the bottle (reported by users online). Other products in the review use materials that we feel are more familiar and bring peace of mind regarding eco-health without the remaining questions we had with the Chicco.

Ease of Use
Newborns can eat as frequently as every 2 hours, and if you're bottle-feeding, chances are you'll be handling (and cleaning) baby bottles upwards of 8 times a day for the first few months. We suggest selecting a product that is effortless to use. You should ask yourself, 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.
The Comotomo ties with the mimijumi and the NUK Simply Natural Glass for the easiest bottles to use. All three earned matching high scores. Bottles with a wide neck opening are much easier to mix formula or pour breastmilk into, reducing waste and eliminating the mess. However, those with narrow neck openings, like the Evenflo Vented + Glass and Lifefactory, can result in liquid loss or mess. The most complicated bottle in our testing is the Dr. Brown's Natural Flow as it has many parts and pieces to assemble, disassemble, wash, and dry, taking more time than any other bottle we have used.
The volume markings are a bit difficult to read when the bottle is empty.The volume markings are on the silicone sleeve, rather than directly on the glass, as is the case in most bottles.There is not much contrast between the volume markings and the rest of the bottle, so you must catch the light in order to read them.
If you want to monitor how much liquid your baby is consuming, we suggest selecting a bottle with distinct volume markings. Also, ask yourself, is it comfortable to hold? How 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.

Many babies use bottles multiple times a day for more than a year. Even breastfed babies often use bottles when their mom is away or sleeping. This reality means selecting a baby bottle that you and your baby are happy with is essential for successful feedings . It helps to consider parent-driven factors, such as leaks, level of effort to clean parts, and convenience, in your decision-making process. However, on the baby's end, nipple type is equally important because not every nipple will work for every baby. 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, and we hope that our findings help you make a good choice for your family.
