Nûby ID00923 Bottle Teats Silicone Large Neck Adjustable + 4 Months x 2

Introducing the first and only wide neck non-drip nipple uniquely designed to prevent drips and spills. The Nuby non-drip feeding nipple features a built-in pressure sensitive valve which only allows fluid to pass through when baby is feeding. As soon as baby stops, this special valve closes, ensuring a leak resistant bottle. In addition, the Non-Drip feeding Nipple features anti-colic vents along the base which help prevent a vacuum from forming in the bottle. This reduces the amount of air the baby ingests and thus, reduces gas and the chances of colic. It also features soft nubs on the surface of the nipple which help soothe baby's tender gums during teething. Like all Nuby nipples, the non-drip feeding nipples are soft and natural in shape which helps to ease the transition form breast to bottle feeding. Fits all Nuby wide neck bottles. Suitable for children aged 4 months and above babies.
