The innovative nipple of the Philips Avent SCY930/01 baby bottle mimics your baby's natural sucking rhythm, supporting a harmonious transition between breastfeeding and bottle feeding. The bottle is designed to act like the mother's breast, facilitating the combination of both feeding methods. It supports your little one's natural and instinctive sucking rhythm. Milk is released only when the baby actively sucks, and when they pause to swallow and breathe, the milk flow automatically stops. The bottle is made entirely of glass, ensuring the highest quality and safety for your baby.
