When you bottle-feed your baby, it is imperative to use bottle nipples designed for your infant's age and sucking ability. Newborns need a slower flow and older babies can handle a faster milk flow, so choose a bottle nipple with the flow that matches your newborn's needs. A nipple that is the wrong style or fit could cause your baby to drink air along with the milk. The wrong nipple might also cause your newborn to eat too quickly, which often leads to gas.
Use the Appropriate Size
Nipples come in different sizes ranging from the preemie nipple, which is designed for premature babies, newborn nipples, which are appropriate for babies from newborn to 6-months-old, and nipples for babies who are 6-months-old or older. Each nipple has a different-sized hole in it. The best bottle nipple for a gassy newborn is one that is age-appropriate. If you use a nipple that is too large for a newborn, he will gulp and choke, triggering more gas.
An ideal nipple for a gassy baby is one that fits into her mouth correctly. There are a variety of nipple styles to choose from, some that help prevent gas. Vented, or anti-vacuum nipples, are designed to prevent nipple collapsing, which often triggers gas. Orthodontic nipples are flattened and designed to resemble the nipple of the breast. Angled nipples are slightly slanted to fit more comfortably into your baby’s mouth. Whichever nipple fits the best in your newborn’s mouth is the nipple that will best prevent gas.
Air must flow through the bottle to replace the milk that you baby sucks out. Check that the nipple you use isn’t so tightly secured that it prevents any air from reentering the bottle. In addition, make sure that the nipple you use flows slow enough that it takes about 20 minutes for your baby to complete his feeding. If the flow is too rapid, your baby may gulp air along with the milk, leading to even more gas.
Although the correct bottle nipple is imperative to prevent gas, consider the bottle itself as well. Angled bottles are designed to decrease the amount of air that your baby sucks in. In addition, plastic liner inserts allow you to squeeze out any unwanted air from the bottle as your baby feeds. Even the best bottle nipple will not cause your baby’s gas to completely disappear -- unfortunately, gas is a natural symptom of digestion that can’t always be avoided.
