Brand: Dr Brown's Natural Flow

ANTI-COLIC GLASS BABY BOTTLE. Anti-Colic internal vent system is clinically proven to reduce colic. Decreases spit-up, burping and wind. CONSISTENT FLOW RATE. Vacuum-free feeding is closest to breastfeeding and Dr. Brown’s silicone teats provide a consistent flow so babies can feed at their own pace. 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.
