The Munchkin LATCH™ Pump Adapter is designed to help you reach your breastfeeding goals. We know that one of the challenges of pumping is transferring pumped bottles of milk into the bottles your baby prefers. That’s why we have developed this breast pump adapter. It helps you connect your LATCH™ bottle directly to most leading breast pumps, so you can pump directly into the LATCH™ bottle. No precious milk will be lost in the transfer, and it means less bottles to clean at the end of the day.
