The innovative MAM Anti-Colic Bottle was developed together with medical practitioners and developmental psychologists to meet baby’s feeding needs at every stage. All bottles utilize MAM’s patented, skin-soft silicone nipple for an easy transition from breast to bottle and feature leak-proof caps that help keep bottles clean when not in use. Patented ventilation holes in the bottle’s base regulate the pressure balance of baby’s milk, allowing it to flow evenly without bubbles or air pockets for reduced gas and colic symptoms.
