This newborn kit is the perfect way to start feeding and soothing your child. Thanks to the Natural Response teat, babies can feed at their own pace, as they would breastfeeding, making it easier to alternate breast/bottle. The unique opening of the teat releases milk only when the baby is actively suckling. Thus, when they stop to swallow or breathe, the milk flow also interrupts. The wide, soft and flexible teat of the Philips Avent bottle is designed to replicate the shape and feel of a breast, allowing baby to suck and feed comfortably.
