Dr. Brown's Natural Flow baby bottles are the only bottles designed by a doctor to help reduce colic, spit-up, burping and gas. Dr. Brown's bottles feature the patented internal vent system, which creates positive-pressure just like breastfeeding.

This fully-vented bottle design produces a more comfortable feeding by eliminating the vacuum and excess air ingestion. It's the venting system your baby deserves, in a choice of bottles to fit your lifestyle.

Dr. Brown's bottles are also easy to clean and dishwasher safe.

Includes 2 Standard 3.5-ounce Dr. Brown's Natural Flow baby bottles with Level-One nipples.
