Munchkin Latch Bottles

http://www.munchkin.com/uk/products/feeding/latch.html A correct latch is achieved when mums nipple reaches all the way back to baby's soft palate. The accordion-style teat on the LATCH™ bottle stretches like the breast, helping baby latch easily & correctly. When breastfeeding, baby controls the flow of milk by applying pressure to the base of mum’s nipple. The LATCH™ bottle mimics mum by releasing more milk as baby pushes against the teat base. While feeding, the accordion-style teat flexes as baby moves her head. This allows baby to maintain her latch, decreasing ingestion of air & risk of colic. The one-way, anti-colic valve located at the bottom of the LATCH™ bottle allows for milk to flow while ensuring air bubbles do not travel through.
