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. This Newborn Bottle Gift Set has all of the essentials you will need for your newborn baby. Includes: 2 LATCH 4oz Bottles with Stage 1 Nipples, 2 LATCH 8oz Bottles with Stage 2 Nipples, 1 LATCH Pacifiers 0+ months, 1 LATCH Bottle and Valve Brush, 2 LATCH Pump Adapters, and 4 LATCH Sealing Discs. Better Latch: Nipple stretches like the breast helping baby latch correctly. Like the breast: Pressure against the nipple releases milk as baby sucks, just like the breast. Less colic: Nipple moves with baby to provide a continuous latch to help reduce the symptoms of colic (Anti-colic valve prevents air bubbles to reduce gas and fussiness).
