How does a vent in a baby bottle help with gas?

While a baby is sucking on a bottle, air can get trapped in the nipple. If there is no vent or valve in the bottle or nipple, the baby will suck down this air along with the milk, which can cause gas and discomfort. Vents work to reroute the air out of the nipple and bottle, so the baby sucks just the milk. Some bottles, like Dr. Brown’s, have a removable vent. Most bottles have a built-in valve in the nipple where trapped air can be released.

Does warming a bottle help to reduce gas in a baby?

“The temperature of the milk does not seem to have any difference on the impact of the baby developing gas or not,” says Cindy Scott, RD, CLC. She is a registered dietitian, certified lactation consultant, and baby-feeding expert. “Slightly warmed breast milk seems to be the most widely accepted,” Scott says. Instead, help reduce gas and discomfort in your baby by making sure they get tummy time; taking breaks while feeding; frequently burping throughout feeds; using a slow-flow nipple; and taking 15 to 20 minutes to feed your baby.

What can I expect to pay for baby bottles for gas?

Consider a few key factors when it comes to price, like brand, material, and design. Some materials, like glass, may be more costly upfront than plastic baby bottles. Additionally, the price of a baby bottle for gas will also depend on how many bottles are included. Typically, if you buy multiple in a pack, you save money instead of buying each bottle individually. Overall, baby bottles for gas range from a few dollars to approximately $45.

The 9 Best Baby Bottles for Gas of 2023

Baby bottles for gas are like a fairy godmother for parents and caregivers looking to relieve gas from their baby's belly. Gas happens when the air becomes trapped in babies' stomachs or intestines, usually caused by too much air in their milk during feeding. While gas can be a huge source of discomfort for your baby, it is incredibly common among newborns due to their immature digestive systems.

“If you have a baby who struggles with gas, make sure that you are bottle-feeding the baby in an upright position and hold the bottle horizontally, as well as allowing frequent breaks to avoid the baby feeding too quickly," explains Cindy Scott, RD, CLC, a registered dietitian, certified lactation consultant, and baby-feeding expert. "Another way to avoid gas when bottle feeding is to burp frequently throughout the feed and at the end of the feeding."

The good news is that you can help alleviate symptoms of many common feeding issues, including gas, with the right baby bottle. When considering baby bottles for gas, check out the material, how easy it is to clean, and additional features to help with gas, such as a vent or valve. We carefully considered design, material, ease of cleaning, features, and value when reviewing products.

The Dr. Brown's Original Baby Bottle Newborn Feeding Set earned our top spot thanks to the bottles' special patented vent system. The bottles have a uniquely-designed vent system that mimics breastfeeding and works as they suck the air out of the milk or formula to help eliminate colic, gas, and spit up.

This newborn feeding set comes with three 8-ounce bottles, two 4-ounce bottles, two nipples, storage caps, and cleaning brushes. While there’s some extra cleaning involved with these bottles and the smaller parts, the bottles are dishwasher safe.

The price for these bottles is hard to beat, and they may help beat gas, too, as they are designed to limit airflow. Printed with colorful designs, the bottles have caps to keep the nipples clean and are BPA and PVC-free.

Many customers say these bottles work just as well as more expensive bottles but at a fraction of the price. They say they’re easy to clean and durable. While some report issues with the nipples collapsing, the manufacturer lists several simple-to-address reasons this may be happening, including the nipple not filling and the cap ring being on too tightly.

Cons

Drips around the rim and ring

Gas is bad enough, but your baby suffering from colic takes things to a whole new, uncomfortable level. While colic is defined by lengthy bouts of crying and is not necessarily caused by gas, babies with colic may have more gas because of all the air they take in when crying. To help provide relief, many parents turn to these anti-colic bottles from Playtex. They’re specially designed with a vent on the bottom to help keep air from getting into baby’s tummy. The bottle is also angled, which further helps with digestion.

The nipples are also designed with multiple holes (three in a 5-ounce bottle) to mimic a mother’s breast more closely than nipples with just one hole.

How We Selected the Best Baby Bottles for Gas

We chose the best baby bottles for gas by studying the design and features of more than 20 baby bottles on the market and researching reviews from customers and competitors. We also monitored shopping trends to bring you the best and most up-to-date offerings on baby bottles. Additionally, we spoke with Cindy Scott, RD, CLC, a registered dietitian, certified lactation consultant, and baby-feeding expert, to find out what to look for in baby bottles for gas. We considered design, size, material, ease of cleaning, and value when reviewing products.

What to Look For in a Baby Bottle for Gas

Vent or Valve

Look for a removable vent or built-in valve or venting system to help extra air escape the bottle. This will reduce the amount of air the baby sucks in while eating, reducing air in the belly that can cause gas and discomfort. If you don’t have a dishwasher or want cleaning to be easy (who doesn't?), opt for a bottle with a built-in valve versus a removable vent, so you don’t have another piece to clean.

Slow Flow Nipple

Choose a slow-flow nipple if your baby is gassy. A slower flow of milk means that baby can suck gradually and more consistently without stopping as much. If milk flows too quickly out of the nipple, it can cause the baby to gulp more air and lead to tummy discomfort.

What Experts Say

"A slow flow nipple is preferred to aid the risk of the baby over distending their stomach, which can happen with quick milk feeds resulting in increased gas. It’s important to allow the baby to lead the way with feeds—bottle feedings should take around 15 to 20 minutes, and quick feedings (less than 5 minutes) are not recommended. Milk should flow gradually and slowly to avoid baby having to take excessive gulps and burps every ounce or two.” —Cindy Scott, RD, CLC
