The 10 Best Bottles For Gas & Reflux — According To A Pediatrician
Take a pass on the gas.
There’s nothing more frustrating than when your baby won’t stop crying or spitting up because of an upset tummy. If you’ve tried gas drops or switched their formula, one easy fix is trying a bottle designed specifically to combat gas and colic. The best bottles for gas and reflux help prevent babies from taking in excessive air during feeds to prevent discomfort and pain. We spoke to Jean S. Moorjani, MD, a board-certified pediatrician, to learn more about how these bottles work.
The Expert
Jean S. Moorjani, MD, FAAP, is a board-certified pediatrician at Orlando Health Arnold Palmer Hospital for Children and a fellow of the American Academy of Pediatrics (AAP). Dr. Moorjani earned her medical degree from Virginia Commonwealth University School of Medicine in Richmond, Virginia. She’s an expert on all things pediatric medicine, with a focus on breastfeeding, asthma, and children with unique medical needs.
Why Do Babies Get Gas And Reflux?
It’s always impressive when a tiny baby emits an adult-sized belch. You may be wondering how someone so small can manage it. According to Dr. Moorjani, “Almost all babies will have some amount of gas or reflux because their gastrointestinal tracts are still immature.” It’s when air enters the equation that issues arise, she says, because swallowing air while drinking milk can lead to gas and reflux. The good news is that there’s relief in the long-term: She explains that “the muscle that helps keep the breast milk or formula in the stomach [...] grows stronger over your baby's first year of life.” In the meantime, an anti-colic bottle may do the trick.
How Do Anti-Colic Bottles Work?
There are a few different styles of bottles to help combat air bubbles:
- Vented Bottles: Dr. Moorjani confirms that vented bottles can be helpful because they “filter out the air bubbles so that your baby will swallow less air during feeding.” Note that not all vented bottles are alike. Many bottles have a straw or similar mechanism to vent air out of the milk as a baby drinks. These bottles have extra parts to clean but parents often say it’s a small sacrifice. Other brands vent directly out of the nipple, eliminating extra parts. A baby can accidentally cover these vents with their hands or face, although most brands have several vents to prevent that from happening.
- Air-Free Bottles: As you shop for bottles, “Air-Free” is another label you’ll encounter. In some cases this means that a proprietary venting system ensures the nipple stays full of milk at all times, even when the bottle is held almost vertically. Dr. Moorjani explains that keeping the nipple full of breast milk or formula can “help decrease the amount of air that your baby swallows during feedings.” Another kind of “air-free” bottle has a silicone interior that collapses as the baby feeds, so air bubbles are never present in the first place. Bonus: This kind tends to have fewer parts to clean.
What Features Should Parents Look For In Bottles For Gas And Reflux?
Dr. Moorjani suggests looking for bottles or nipples with a slower flow rate, which can decrease “the amount of air that your baby swallows and hopefully decrease the episodes of reflux,” she explains. It’s helpful to look at the nipple ratings, usually numbered, indicating a slower to faster flow rate. We found many models that have a self-regulating nipple that lets a baby control the flow of milk so they aren’t overwhelmed, and many of the anti-colic bottles on our list specifically aim to allow for a slower flow rate.
Before you know it, you’ll be in the land of sippy cups. In the meantime, we’ve found the best bottles for gas and reflux that don’t leak and will help you avoid those extra loads of laundry. And if you opt for a Comotomo bottle, don’t forget to pick up a bottle warmer that fits that specific bottle size.

01The Anti-Colic Bottle Clinically Proven To Reduce Gas & Spit-Up
This tried-and-true Dr. Brown anti-colic vent bottle has a clinically proven venting system to prevent gas, spitting up, and colic. The BPA-free plastic bottle uses a vacuum-free, contoured silicone nipple that allows for a consistent flow and the colic inserts can be removed if a baby outgrows the need for it. The bottle is safe to boil and use in the dishwasher, as well as in electric and microwave bottle warmers. The wide neck makes it easier to clean, but reviewers do warn this is a bottle with a lot of small parts to wash. Even still, one fan reported: “It was a total game changer.” It comes with nipple level 1, and you can buy more sizes as baby grows.
Helpful Review: “[...] I switched from another well-known anti colic bottle at my pediatrician’s recommendation, and Dr Brown’s works SO much better. Within a week my colicky, fussy and generally miserable newborn was like a whole new baby. She had these ‘episodes’ where she would scream with gas pain for hours (and nothing helped), she spit up constantly, so we switched to these bottles and everything was better. She gets gassy still occasionally, but gas drops and tummy massage take care of it — no more hours-long scream sessions.[...] If you have a little one struggling with gas pains, constant spit up and general fussiness during/after eating, I say give these bottles a shot. For me and my baby, it made a difference.”

Helpful Review: “Best baby bottle ever! [...] This bottle has a nipple that is shaped like the breast and feels like a breast so my son had no problem using it. [...] doesn't leak and the BEST thing about this bottle is the anti colic system. It is better than any bottle I have ever tried. Usually you have to take the bottle out of babies mouth to let the air bubbles come out ..but you don't have to lift a finger with this bottle. NO air will ever get in, so you don't have to take the bottle out of babies mouth during the entire feeding. Great for colicky babies and babies with reflux. I’ve tried many anti colic bottles and they all still get air bubbles..this is the only one that doesn’t. Worth every penny.”

Helpful Review: “My baby having been a preemie always struggled with some reflux. Right out of the NICU we eventually transitioned from the enfamil hospital provided nipples to the first stage of these bottles.

05A Set Of Glass Bottle That Reduce Gas Without Extra Parts
The NUK Simply Natural glass bottles pair a dishwasher-safe glass bottle with a vented silicone nipple that has multiple holes for more natural feeding.

One clever mom noted the glass bottles can also be used for other purposes later on, like a baby food jar. This bottle comes with a medium flow nipple but slow flow nipples are available as well. You can also get this bottle in a plastic version.
Helpful Review: “We have four kids and have used several different brands of glass bottles for breast-milk feeding over the years. This is the first brand and design we’ve used that doesn’t leak from some unidentifiable crevice. Wish I’d discovered these before our fourth baby and saved ourselves a lot of mess and frustration over the years. Best of all it’s three simple parts - a bottle, a nipple, and a ring - and you don’t have to deal with all the ‘anti-colic’ extra pieces like those funnel-and-straw looking inserts that alway leak and are such a pain. [...]”

07A Set Of Vented Silicone Bottle With An Extra-Stable Base
Parents rave about these silicone baby bottle with anti-colic vents that are placed around the nipple so a baby can’t accidentally cover them all up.

Non-collapsible ridges in the nipple maintain flow and help keep a baby latched; and you can add snap-on handles down the road to transform them into sippy cups. One thing to note: because silicone resists heating, the brand recommends heating milk before it’s placed in this bottle, rather than warming it directly in the bottle. This 5-ounce bottle comes with a slow flow nipple and you can buy other nipples.
Helpful Review: “My baby has reflux, bad colic, bad gas and spit up issues so we have been looking for a good bottle to help her with all her issues. We had tried a few different bottle before coming to these. We love the 360 holes for venting air they help with the gas and colic. These are easy to clean, don't have a lot of small parts to deal with, stand well (unlike other competitors) and are soft to touch for baby. I completely recommend these bottles!!”

This isn’t just a pretty impulse buy either — this set is tried and true with over 19,000 five-star reviews.
Helpful Review: “Has the necessary brushes to clean all the different baby bottle parts for various brands. I love that it doubles as a cute plant display for my window sill instead of another hideous brush to add to the sink clutter.”
