The Natural Response dummy only releases the milk when the baby is actively drinking. The baby drinks, swallows and breathes with its natural rhythm like on the chest. Easy to combine breastfeeding and bottle. Unique pacifier opening that releases milk only when baby is actively drinking. When it stops to swallow and collect air, the milk also stops flowing. The wide, soft and flexible dummy of the Philips bottle mimics the shape and texture of the female breast and helps the baby to suck and drink quietly. Anti-colic bottles for babies keep the air away from the baby’s stomach when breastfeeding, reduce colic and discomfort. The dummy hole releases the food only when the baby sucks. This allows us to avoid milk loss at home or on the go. Made of high-quality borosilicate glass, the Philips Avent glass bottle is heat resistant and heat shock.
