The next generation of teat - the result of extensive research in latching, peristaltic movement and swallowing. The SofTouch™ Peristaltic PLUS teat aims to be the closest teat to a mother's nipple to reduce nipple confusion and promote easy bottle feeding. S size for babies that drink 100ml in approx 10 mins. The S teat tip is a round hole, meaning the milk will drip out without too much effort from your baby, perfect for when they are very young and their jaw muscles are less developed.
