The Philips Avent Natural Response Baby Bottle with a 125ml capacity is thoughtfully designed for newborns and up (0m+). Its innovative Natural Response nipple works with your baby's unique feeding rhythm, releasing milk only when actively drinking, just like the breast. This supports easy switching between breast and bottle. The soft, flexible silicone nipple is designed to prevent nipple collapse, while the anti-colic valve is engineered to reduce air ingestion, helping to ease discomfort and fussiness. The ergonomic bottle shape is easy to hold in any direction and simple to clean and assemble, making feeding time more enjoyable for both parent and baby. Made from BPA-free materials for your child's safety and peace of mind.
