The Philips Avent Natural Baby Bottle supports your baby’s natural feeding rhythm, letting them 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 mimics the feel of the breast, making it easy to switch between breast and bottle. A no-drip nipple design prevents spills, while the built-in anti-colic valve helps reduce air intake for a more comfortable feeding experience. Includes three 11oz Natural bottles with fast flow (Flow 4) nipples.
