The Avent Natural Response bottle features the “Natural Response” nipple, which lets your baby control the pace of milk flow , similar to breastfeeding. The nipple has a unique opening that only releases milk when the baby sucks; when the baby pauses to swallow or breathe, the flow stops
It includes a wide, breast-shaped silicone nipple to help with natural latch-on, and an anti-colic valve integrated to help reduce air ingestion and potential discomfort.
The bottle is easy to clean thanks to its wide neck and fewer parts.
It’s made for babies 1 month and older (1 m+).
