Avent Philips Avent Natural Response Baby Gift Set - 2x 4oz, 2x 9oz Baby Bottles, Soother and Bottle Brush, SCD657/11 Flows like a breast, aids to reduce feeding issues. The Philips Avent Natural Response Teat supports babies' unique suck, swallow and breathe rhythm, while the AirFree vent is designed keep air away from their tummy for extra protection against colic, gas and reflux. 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. 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 AirFree vent is designed to offer protection against feeding issues by preventing air from getting into your little one's tummy whilst feeding upright. 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 Avent bottle. Mix and match our breast pump, Philips Avent bottle and cup parts, and create the product that works for you, when you need it. The ergonomic Philips baby bottle is easy to grip at any angle to give maximum comfort during feeding - easy for both your hands, and tiny hands, to hold! The wide baby bottle neck makes filling and cleaning easy, and as the AirFree vent is a single piece, assembly of the bottle is quick and easy with only a few parts. 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: 2 4oz/125ml bottles, 2 9oz/260ml bottles, 1 Bottle brush, 1 ultra soft pacifier 0-6m *0% BPA, following EU regulation 10/2011
