Philips Avent Natural Response offers a feeding experience that uniquely mimics the breast. Its unique nipple releases milk only when baby actively sucks, allowing baby to drink, swallow and breathe naturally and at their own pace. This makes the transition between breastfeeding and bottle feeding easier. The teat, designed with a shape similar to the breast, ensures a natural and comfortable latch on for the baby. In addition, it has an anti-colic valve that effectively reduces air intake, helping to prevent colic and discomfort during feeding.
