The Best Anti-Colic Baby Bottles: 4 Compared (and One to Skip)
We compared four current anti-colic bottles on venting performance, latch, cleaning, leak resistance, and warmer compatibility to find the one worth buying.
The verdict in 30 seconds
What mattered most
- Anti-colic effectiveness
- Parts to assemble & clean
- Breast-like nipple / acceptance
- Leak resistance
- Warmer & sterilizer fit
- Material
Anti-colic bottles all promise fewer bubbles, less gas, and calmer feeds, but they get there in very different ways, from Dr. Brown's multi-part internal vent to Comotomo's soft silicone body. We synthesized independent testing and thousands of owner reports to sort the genuinely effective designs from the ones that trade colic control for cleaning headaches. Two of these earn a clear buy, one depends on your baby, and one we would skip for colic specifically.
The most thorough anti-colic venting on the market, if you can tolerate the extra parts.
Best for: Babies with real gas, reflux, or colic where venting performance matters more than convenience.
- Internal vent system is the most consistently praised for reducing gas, spit-up, and reflux
- Vent can be removed as your baby outgrows colic, so the bottle keeps working long-term
- Nipple delivers a genuinely slow, steady flow that suits newborns and paced feeding
- The internal straw and insert mean the most parts to wash and reassemble of any bottle here
- The extra pieces can leak if the collar is over-tightened or the vent is seated wrong
The easiest bottle to clean and the one breastfed babies accept most readily.
Best for: Breastfed babies transitioning to a bottle, and parents who hate scrubbing narrow bottles.
- Soft, breast-like silicone body and wide nipple win over many bottle-refusing, breastfed babies
- Ultra-wide neck lets you clean the whole bottle by hand without a brush
- Dual anti-colic vents on the nipple are simple, with far fewer parts than vented-straw designs
- The squat, wide base does not fit many bottle warmers, sterilizer racks, or cup holders
- Owners note nipple flow can speed up or drip if the collar seal is not seated just right
Solid venting with fewer parts than Dr. Brown's, but the AirFree vent is a mixed bag.
Best for: Parents who want anti-colic help and upright feeding without Dr. Brown's full parts count.
- Fewer pieces than internal-straw bottles while still reducing air intake during feeds
- AirFree vent keeps the nipple full so babies can feed more upright, which some reflux babies prefer
- Wide, ridged nipple is widely accepted and the range is easy to find and expand
- Reviewers report the AirFree vent can leak or overflow if the bottle is tipped or filled too high
- Some owners find the nipple flows faster than expected, which does not suit every newborn
Clever self-sterilizing trick, but the vented base is the one owners most often see leak.
Best for: Parents who value the microwave self-sterilizing feature over best-in-class colic control.
- Self-sterilizes in the microwave in a few minutes with just a little water, which is genuinely handy for travel
- Soft SkinSoft nipple has a high acceptance rate with babies
- Affordable and widely stocked
- The multi-piece vented base is the most common leak complaint in owner reports if not assembled perfectly
- Anti-colic performance is reported as less consistent than the dedicated venting leaders

How we judged the field
We do not run our own lab. Instead, we synthesized independent testing, expert feeding guidance, and aggregated owner reports across thousands of reviews to see where each bottle actually earns its keep. For an anti-colic roundup, the criteria that mattered most were: how effectively the venting reduces swallowed air, how the nipple flows and whether babies accept it, how many parts you have to wash and reassemble, how well the bottle resists leaks, and whether it fits real-world gear like warmers and sterilizers. We weighted venting effectiveness and leak resistance heavily, because those are the whole point of buying an anti-colic bottle rather than a plain one.
A note on flow: every bottle here comes in newborn slow-flow versions, and matching nipple flow to your baby’s age matters as much as the brand. We judged each on its slow-flow starting point.
Dr. Brown’s Natural Flow Anti-Colic Options+ Narrow Bottle — buy
This is the bottle reviewers and owners reach for when colic, gas, or reflux is a genuine problem rather than a marketing worry. Its internal vent system channels air away from the milk, and it is the design most consistently credited with cutting spit-up and fussing. The honest trade-off is parts: the internal straw and insert give you the most pieces to wash of anything here, and if you over-tighten the collar or seat the vent wrong, it can leak. The saving grace is that the vent is removable, so as your baby grows out of colic you can simplify the bottle instead of buying a new one. For the job of controlling air, nothing here does it better.
Comotomo Natural Feel Silicone Baby Bottle — buy
Comotomo solves a different problem: acceptance and cleaning. Its soft silicone body and wide, breast-like nipple win over a lot of breastfed babies who reject firmer bottles, and the ultra-wide neck means you can wash the whole thing by hand without a brush. Its dual nipple vents are far simpler than a vented straw, so there is very little to reassemble. Two caveats keep it from being the outright winner for colic: the squat, wide base does not fit many warmers, sterilizer racks, or diaper-bag pockets, and owners note the flow can drip or speed up if the collar is not seated cleanly. As a naturalness-and-convenience pick, though, it is excellent.
Philips Avent Anti-colic Bottle with AirFree Vent — it depends
The Avent sits between the two leaders. Its AirFree vent keeps the nipple full of milk so babies can feed in a more upright position, which some reflux-prone babies tolerate better, and it does this with fewer parts than Dr. Brown’s. Whether it is right for you genuinely depends on your setup: a meaningful share of owners report the AirFree vent leaking or overflowing if the bottle is tipped or overfilled, and some find the nipple flows faster than they want for a newborn. Used carefully and filled sensibly, it is a capable anti-colic bottle; used casually, the vent can frustrate you.
MAM Easy Start Anti-Colic Bottle — skip
MAM has real strengths, a soft, high-acceptance nipple and a clever base that self-sterilizes in the microwave in a few minutes, which is genuinely useful for travel. But for anti-colic specifically, its multi-piece vented base is the part owners most frequently report leaking when it is not assembled just right, and its venting performance is described as less consistent than the dedicated leaders. If self-sterilizing is the feature you care about above all, it is defensible. If you are buying primarily to control colic, the other three do that core job more reliably, so we skip it here.
Dr. Brown’s Options+ vs Comotomo: which should you buy?
These are the two we would actually put on a registry, and they suit different households. Dr. Brown’s is the choice when the symptoms are real: its internal vent is the most effective at reducing the swallowed air behind gas and reflux, and you accept more washing-up as the price. Comotomo is the choice when your baby is fussy about the bottle itself or you simply cannot face scrubbing narrow bottles at midnight: it is the easiest to clean, the most breast-like, and the most readily accepted by nursing babies, with less aggressive venting. Put simply, buy Dr. Brown’s if colic is the problem, and Comotomo if acceptance and cleaning are. If you only want one bottle to cover most babies, start with Dr. Brown’s and keep a Comotomo on hand as backup.
What to look for
- Venting that matches the problem. Internal-vent designs control air best; simpler nipple vents trade some performance for far less cleaning.
- Parts count. Every extra piece is another thing to wash, lose, and reassemble at 3 a.m. Be honest about your tolerance.
- Correct nipple flow. Start with slow-flow for newborns; too-fast flow causes gulping and gas no matter how good the bottle.
- Leak resistance in the real world. Read owner reports on leaks specifically, since many vented bottles leak only when assembled or filled wrong.
- Gear fit. Confirm the bottle fits your warmer, sterilizer, and bag before you commit to a full set, especially with wide-base silicone bottles.
- Material preference. Silicone feels soft and is easy to clean; plastic and glass options fit more accessories and warmers.
Our final take
For an anti-colic bottle, buy for the job first and convenience second. Dr. Brown’s Natural Flow Anti-Colic Options+ is our pick because its venting is the most effective at doing the one thing you are paying for, and the removable vent means it stays useful after the colic passes. Comotomo is the runner-up and the smarter buy for breastfed babies and cleaning-averse parents who can live with its bulky base. Philips Avent is a reasonable middle path if you want fewer parts and upright feeding, provided you fill it carefully. MAM’s self-sterilizing trick is neat, but its leak-prone base and softer colic control put it last for this specific purpose. Start with the bottle that fits your baby’s actual struggle, and you will not need to rebuy.
Questions, answered
Do anti-colic bottles actually reduce colic?
They can help with the air-related part of the problem. Vented designs reduce the bubbles a baby swallows, and independent testing and owner reports link that to less gas, spit-up, and fussing for many babies. This is general product information, not medical advice; true colic has many causes, so if your baby is inconsolable, feeding poorly, or you are worried, consult your pediatrician.
Which of these is easiest to clean?
Comotomo, by a wide margin. Its ultra-wide silicone body lets you reach every surface by hand without a bottle brush, and it has the fewest parts. Dr. Brown's and MAM sit at the other end because their venting systems add an internal straw or a multi-piece base that all need washing.
Are the extra parts in Dr. Brown's worth the hassle?
For a baby with real gas or reflux, most owners say yes, because the venting is the most effective here. The bonus is that the internal vent is removable, so once your baby outgrows colic you can drop the extra piece and keep using the same bottle as a simpler design.
Why is MAM the one to skip if it is so popular?
MAM is well liked overall and the self-sterilizing feature is genuinely convenient. For anti-colic specifically, though, its vented base is the part owners most often report leaking when it is not assembled perfectly, and its venting is less consistent than the leaders. If colic control is your top priority, the others do it better.
Which bottle is best for a breastfed baby who refuses bottles?
Comotomo is the usual first recommendation. Its soft, breast-like silicone body and wide nipple most closely mimic nursing, and it has the highest acceptance in owner reports among refusers. MAM's soft nipple is a reasonable second option to try.
