The innovative Mam Anti-Colic Bottle was developed together with medical practitioners and developmental psychologists to meet baby's feeding needs at every stage. Mam Anti-Colic bottles have a SkinSoft textured nipple that is accepted by 94 percent of babies* and a patented vented base that regulates pressure ensuring babies do not get air in their tummies while feeding. The wide openings make it easy to clean, fill and assemble. The bottle self-sterilizes in 3 minutes in the microwave in 3 easy steps for easy cleaning. Includes 1 medium-flow nipple. *Market research 2009-2017 of 1,508 babies. Color: Pink. Gender: Female.
