Introducing the new Munchkin LATCH Bottle - designed to help you reach your breastfeeding goals. Experts agree that a better latch eases the transition between breast and bottle, and back. That's why our accordion nipple pumps and moves just like the breast, stretching back to your baby's soft palate for a correct latch. The bottle also features a one-piece, anti-colic valve - so no air travels through the breast milk, reducing the risk of colic.
