The Philips Avent Natural Baby Bottle supports your baby’s natural feeding rhythm, allowing them to control the pace of milk flow just like breastfeeding. Its unique opening and tip release milk only when your baby actively drinks—so no milk flows while they pause to swallow or breathe. The soft, wide, breast-shaped nipple makes it easy to combine breast and bottle feeding, while the no-drip design helps prevent spills for peace of mind at home or on the go. Featuring an anti-colic valve that keeps air out of your baby’s tummy to reduce discomfort, this set includes four 9oz pink Natural bottles with medium flow (Flow 3) nipples.
