Philips Avent Natural Response review

Philips Avent Natural Response takes a different approach to calmer feeds. Rather than a vent, the US product page centers on the nipple: Philips says its opening releases milk only when the baby actively drinks, so when the baby pauses to swallow and breathe, the milk pauses too. That can help babies who gulp or get overwhelmed by flow. The nipple is wide, soft and flexible and designed to mimic the shape of a breast. Philips is specific about flow: switch to the First Flow nipple if your baby takes longer than 20 minutes to drink 50 ml with the standard nipple, and move up a flow if the baby plays with the nipple instead of drinking. The SCY903/04 set includes four 9 oz bottles with Medium Flow nipples for 3 to 6 months for $32.95, about $8.24 per bottle. Bottles also come in 4 oz and 11 oz. The page we checked did not describe an anti-colic vent, which is why it ranks below vented bottles. We compared documented features and published prices.
