Flexible Slim Neck Nipple Size S

Backed by over 60 years of research on baby's natural suckling motion, our Flexible Slim Neck Nipple is so soft it flexes to the movements of babies' mouth and bends naturally to baby's mouth movement. The nursing bottle's Air Ventilation System (AVS™) reduces intake of gas, a potential cause of colic.

For 0+ months. The opening of the nipple is round-cut which allows milk to flow out consistently and gradually. Newborns have yet to develop any jaw msucles, thus the nipple is designed to support their sucking ability at this age.
