Breastfeeding is best for babies and can be a rewarding and fulfilling experience for mums, but there may be times when you may want to express breast milk either for a break or for your partner to share the feeding experience. The unique teat and anti-colic valve helps to make breast and bottle feeding work better together, for you and for baby. The latch bottle is designed to mimic the breastfeeding experience. Unlike other wide-mouth bottles which look like the breast, the unique accordion teat moves and functions most like the breast, helping ease baby's transition from breast to bottle and back. The teat stretches, moves and pumps, so baby can and feed just like on your breast. The stage 1 teat's flow has been reduced to mimic the slower flow of from the breast. When breastfeeding, baby controls the flow of milk by applying pressure to the base of mum's nipple. The bottle mimcs mum by releasing more breast milk as baby pushes against the teats base. The bottle also features the unique anti-colic valve - a base venting, one-piece valve that prevents air bubbles traveling through the milk, reducing the chance of colic.
