Philips Avent Natural Response Bottle 1m+ 260ml Provides calm, comfortable feeds. The Natural Response Teat supports baby's unique drinking rhythm, while the AirFree vent is designed for extra protection against colic, gas and reflux by keeping the teat full of milk, not air for easier upright feeding and less air ingestion. Finding the right teat is important. See more info below. The Natural Response teat works with your baby's natural feeding rhythm, making it easy to combine breast feeding and bottle feeding. The nipple has a unique 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 teat is designed to mimic the shape and feel of a breast, helping the baby to latch on and feed comfortably. The AirFree vent is designed to offer extra protection against feeding issues by preventing air from getting into your little one's tummy whilst feeding in an upright position. The teat 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. 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 bottle. All of the Natural Response Teats are made of soft silicone. If your newborn baby is consistently not taking enough milk throughout the feeding sessions or has complications in getting milk, switch to a teat with a higher flow rate. If persistent feeding issues occur, consult a healthcare professional. We have moved to a pace-based flow navigation system. Start with the teat that comes with the bottle. Try a lower flow if milk is leaking from your baby's mouth or your baby is gulping. Try a higher flow if your baby is playing with the teat instead of drinking or seems frustrated. As we make this change, you may receive either style of pack. The ergonomic bottle is easy to grip at any angle to give maximum comfort during feeding. Easy for your hands and tiny hands to hold. Wide bottle neck makes filling and cleaning easy. Only a few parts for quick and simple assembly, as AirFree vent is a single piece. Mix and match our breast pump, bottle and cup parts and create the product that works for you, when you need it. The Philips Avent Natural Response bottles and teats are made of BPA free** material.
