Choose a Different Bottle
If you are bottle feeding, you may want to take a look at the bottle system or nipple you are using.
There are some great bottles on the market that can help reduce the amount of air ingested by babies, which can reduce the buildup of gas in the digestive system. Look for a system that allows you to feed straight from the bag. Also, look for bottles that have a bend in the body rather than just being straight.
Bottle nipples come in various flow options that are supposedly measured by speed and a baby’s age. These labels are usually pretty accurate, but you may need to try a few different types to find the right shape and flow for your baby. They may not be getting enough milk, swallowing more air, or they may have too much milk coming to them at once, frustrating and upsetting them.
