Philips Avent Natural Response Baby Bottle - The next level of natural to enable seamless combination between breast and bottle feeding. The bottles work with your baby's natural feeding rhythm, making it easier than ever to combine breast feeding and bottle feeding.

Unlike standard bottles, the Natural Response Nipple has a unique opening which only releases milk when the baby actively drinks so that when they pause to swallow and breathe, the milk pauses too. 
The innovative tip and opening responds to the drinking motion of the baby’s tongue – which causes the drinking valve to open and close – so milk is released only when baby is actively drinking, like at the breast. Without the baby’s compression, milk does not drip from the tip.
The no-drip nipple opening is designed to release milk only when the baby is feeding so that you can confidently prevent spills and avoid milk loss whether at home or on the go.
Due to the unique, ergonomic shape, the bottle is easy to hold and grip in any direction for maximum comfort, even for baby’s tiny hands.
The anti-colic valve is designed to keep air away from your baby’s tummy during feeding to help reduce colic and discomfort.
The bottles only have 4 parts, making it easy to clean and assemble.
The Philips Avent Natural range offers different nipple softness and increasing flow rates for every developmental stage of your baby.
