Avent Anti-colic Baby Bottle Flow 4 Nipple, 2 pack

Philips Avent Anti-colic nipple flow 4 is our fast flow nipple, which is great for growing babies drinking from a bottle. The anti-colic valve integrated in the nipple is designed to keep air away from your baby's tummy to reduce colic and discomfort. As your baby feeds, the valve flexes to allow air into the bottle to prevent vacuum build up and vents it towards the back of the bottle. It keeps air away from baby’s tummy to help reduce colic and discomfort. The nipple shape allows for a secure latch and the ribbed design helps prevents collapse for uninterrupted, comfortable feeding. The anti-colic nipple is made of flavorless, odorless, soft, silicone that resists discoloring and Stickiness, a BPA free material.
