Philips Avent Natural Response Nipple 0m, Flow 2

The Natural Response Nipple releases milk only when baby actively drinks. Babies can drink, swallow and breathe using their natural rhythm, like on the breast. Making it easy to combine breast and bottle feeding.
The wide, soft and flexible nipple is designed to mimic the shape and feel of a breast, helping baby to latch on and feed comfortably. Anti-colic valve is designed to keep air away from baby's tummy during feeding, to help reduce colic and discomfort.
