Make bottle feeding easier and natural with the Philips Avent Fast Flow Teats. This AVENT fast flow nipple puts your baby in charge of the pace in which the milk flows, thereby reducing overeating or spit ups. The nipple has a unique valve that flexes to allow air into the bottle, keeping it away from your baby’s tummy for a more healthy approach. This, in turn, reduces colic that is frequently experienced with other feeding products. The unique valve on the nipple matches your child’s feeding rhythm and is clinically proven to reduce fussing. The teats are BPA free for your baby’s safety, simple to clean, and pair nicely with the Philips AVENT Classic feeding baby bottles.
