•Natural Response teat: The unique Philips Avent bottle teat opening only releases milk when the baby actively drinks, so when baby pauses to swallow and breathe, the milk pauses too.
•Works like the breast: The teat releases milk when baby actively drinks, this is different from the traditional free-flow teats. As with breastfeeding, it can take time for a baby to get used to this.
•Anti-colic valve: The baby bottle is designed to keep air away from the baby's tummy during feeding to help reduce colic and discomfort.
•No-drip teat: The teat only opens to release milk when the baby is feeding, preventing spills and lost milk.
•Heat resistant glass: Made of borosilicate glass, the Philips Avent glass bottle is heat and thermal shock resistant.
