The soft, naturally shaped AVENT nipple makes it easier to switch between breast and bottle feeding, and promotes healthy, active feeding. The built-in valve flexes with baby's natural feeding rhythm and lets baby control the flow of milk, which can help reduce the risk of overeating and spit-up. The valve also prevents a vacuum from forming in the bottle to keep air out of baby's tummy. This reduces colic and gas after feeding. Fast Flow Rate is ideal for babies 6m+.
