ANTI-COLIC BABY BOTTLE. Dr. Brown's anti-colic internal vent system is clinically proven to reduce colic and helps reduce spit-up, burping, and gas. AIR-FREE FEEDING AND CONSISTENT FLOW. The silicone nipple and vent system work together to provide vacuum-free feeding and a consistent flow rate so babies can feed at their own pace without swallowing excess air. SMOOTH BREAST TO BOTTLE TRANSITION. The breast-like nipple shape encourages a proper latch for a more natural bottle-feeding experience and eases the transition from breast to bottle and back again. PRESERVES NUTRIENTS. The anti-colic vent system is proven to help preserve nutrients in breast milk and aids in digestion for a better night's sleep. DISHWASHER SAFE. Safe for use in dishwasher (top rack only), electric and microwave sterilizers, or boiling water. BPA Free. Recyclable. Pack of Four, 4 oz/120 mL Baby Bottles with Level 1 Slow Flow Nipples, 0m+
