The Philips Avent Natural Response Teat By Fratelli supports babiesâ 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 â 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 oneâs tummy whilst feeding upright. Every baby feeds differently and develops at their own pace. Weâve 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 â 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 1 Baby Bottle 4oz/125ml. *The Natural Response Nipple releases milk only when your baby actively drinks. Babies can drink swallow and breathe using their natural rhythm like on the breast. **0% BPA following EU regulation 10/2011
