Dr. Brown's Natural Flow® Baby Bottle

Dr. Brown’s Natural Flow Baby Bottles feature an innovative, fully-vented design that enhances a baby’s feeding experience while reducing feeding problems. With a patented 2-piece internal vent system that creates positive-pressure flow, Dr. Brown’s bottles eliminate air bubbles in the formula or milk and help to reduce colic, spit-up, burping, and gas. This system is also proven to help preserve bottled milk nutrients, including vitamins C, A, and E, which are critical for infant health. By creating a vacuum-free, fully vented bottle, Dr. Brown offers the baby an easy digestion-feeding experience that is closer to breastfeeding than any other bottle. The patented vent system and silicone nipple also work together to create a controlled flow so babies nurse at their own pace. Dr. Brown's bottles are BPA, PVC, lead, and phthalate free for your baby's safety. Each bottle comes with 1 Level-One silicone nipple, 1 two-piece patented internal vent system, 1 cleaning brush, and instructions.
