Avent Classic+ Teats is designed to prevent air from entering your baby's tummy to reduce colic and discomfort. The valve integrated into the teat prevents a vacuum from forming while your baby is drinking and the air is returned to the bottom of the bottle. This keeps the air inside the bottle and does not get into your baby's tummy, reducing bloating, colic, and reflux.rupted feeding
