The Philips Avent Natural Response nipple only releases milk when the baby actively drinks. Babies can therefore drink, swallow, and breathe using their natural rhythm, like on the breast – making it easy to combine breast and bottle-feeding. This bottle has a unique nipple opening which only releases milk when the baby actively drinks – so when they pause to swallow and breathe, the milk pauses too. The wide, soft, and flexible nipple of the Avent bottle is designed to mimic the shape and feel of a breast, helping the baby to latch on and feed comfortably. Additionally, the anti-colic bottle value is designed to keep air away from your baby’s tummy during feeding, to help reduce colic and discomfort. Every baby feeds differently, and develops at their own pace. We’ve designed a range of flow rates so you can find the perfect one for your baby and personalise your Philips Avent baby bottle. Mix and match our Philips Avent breast pumps, bottles and cup parts, and create the product that works for you, when you need it. The nipple opening is designed to release milk only when the baby is feeding, so you can confidently avoid milk loss, whether at home or on the go. Philips Avent Natural bottles and nipples are made of BPA free* materials. Our new Natural Response Philips Avent bottles are different from free-flow baby bottles. Just like breastfeeding, it could take a few tries to get it right. That’s perfectly natural. Includes: 2x Flow 3 Natural Response Teats *0% BPA
