Anti-colic baby bottle Clinically proven to reduce colic
Dr. Brown's baby bottles are fully-vented and clinically proven to reduce colic.* Dr. Brown's anti-colic internal vent system helps prevent ingestion of air bubbles and eliminates the vacuum effect which helps reduce spit-up, burping and gas. It also means no nipple collapse or fluid buildup in baby's ear.
