Dr. Brown’s Natural Flow Anti-Colic Options+ Narrow Baby Bottle (250ml) provides a feeding experience that closely resembles breastfeeding, helping babies latch naturally and feed comfortably at their own pace. The vacuum-free design and breast-like silicone nipple support smooth, consistent milk flow, easing the transition between breast and bottle. Its patented internal vent system reduces colic, gas, and spit-up while preserving essential milk nutrients for improved digestion and better sleep. As your baby grows, the vent system can be removed—no need to switch bottles. BPA-free and safe for sterilizers, boiling, and top-rack dishwasher use, this bottle is a trusted choice recommended by pediatricians across the U.S.
