That's why Tommee Tippee has combined their award-winning breast-like nipple with the latest revamped in anti-colic innovation to create the NEW Advanced Anti-Colic bottle. The unique 3-piece anti-colic technology draws air away from milk and the star valve keeps milk from traveling up the tube meaning 80% less gas, spit-up and fussing.
