ANTI-COLIC BABY BOTTLE. Anti-Colic internal vent system is clinically proven to reduce colic. Decreases spit-up, burping and gas. CONSISTENT FLOW RATE. Vacuum-free feeding is closest to breastfeeding and Dr. Brown’s silicone nipples provide a consistent flow so babies can feed at their own pace. PRESERVES NUTRIENTS. The anti-colic vent system is proven to help preserve bottle milk nutrients and aids in digestion for a better night’s sleep. BREASTFEEDING BOTTLE. 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. BOTTLE GROWS WITH BABY. With three nipple levels included, Slow Flow, Medium Flow and Medium-Fast Flow, bottle grows with baby! Dr. Brown’s Natural Flow Anti-Colic Options+ baby bottle works best with the internal vent system in place but can be removed as baby’s feeding develops – no need to introduce a different bottle. GIFT SET. Included is Dr. Brown’s HappyPaci 100% silicone one-piece pacifier, shaped like Dr. Brown’s bottle nipple. Introducing baby to a pacifier is easy with the same shape that’s familiar to baby. Store, transport and warm bottles with ease using the included storage/travel caps.
