The new MAM bottle was designed specifically to work just like breastfeeding. Considering the natural stripping action a baby uses to extract milk from mother's breast, MAM has created this nursing bottle featuring a bottom vent and an ultra soft, ergonomic shaped nipple. While the nipple features a silky texture, the vent allows baby to "strip" milk in the most natural way.
The vent means less air, less gas and less spitting up for baby. The nipple and vent work in harmony with each other to help babies transition from breastfeeding to bottle feeding. Whether you are feeding breast milk or formula the bottle vent adjusts perfectly to all flow rates. But most of all babies love this new MAM ULTIvent Bottle
