Sleep and nutrition are vital to your babyﾒs health and happiness. The Philips AVENT 2 Advanced Classic feeding bottle SCF660/27 significantly reduces colic and fussing. This BPA-free feeding bottle consists of only three components for ease of cleaning and has an dormal cap for hygienic storage and transportation. As your baby feeds, the unique skirt on the AVENT Nipple flexes to allow air into the bottle instead of your babyﾒs tummy. Like natural breastfeeding your baby controls the milk flow.
