Created by a physician, Dr. Brown's natural flow baby bottles feature a patented internal vent system that helps reduce colic, spit-up, burping and gas. The positive pressure design allows babies to feed comfortably, because the vent system eliminates the air bubbles and vacuum. All parts are dishwasher safe. Polypropylene. BPA free.
