The NEW Natural Philips AVENT 9-ounce Blue Bottle is the most natural way to bottle feed. The bottle has an extra soft nipple that makes it easy for baby to latch on to, and unique comfort petals to make sure the nipple doesn't collapse as baby feeds. A specially-designed anti-colic nipple flexes as baby sucks, so air ends up in the bottle and not in baby's tummy. The ergonomic shape is easy for parents to hold and little fingers to grasp when they're ready. With a wide neck and fewer parts, the bottle is easy to fill and clean. It's also made from BPA free polypropylene, so it's safe for baby. This bottle works with the entire line of Natural Philips AVENT nipples and caps. Breast-shaped nipple has comfort petals to make feeding more comfortable Twin anti-colic valves keep air out of baby's tummy Curved bottle is easy for both you and baby to hold Wide neck makes filling and cleaning bottles easier Polypropylene material is easy to clean and sterilize Bottle works with all Natural Philips AVENT nipples and bottle rings Included in the Box Three blue Natural Philips AVENT 9-ounce bottles, three Natural slow-flow nipples, and three bottle caps.
