Textured Surface The surface of this baby nipple is textured allowing the baby to easily latch on. Made of 100% Silicon This nipple is made up of 100% silicon which makes it flexible and soft. AVS System Gas intake is reduced because of the AVS system which eventually stops colic. Sometimes it so happens that the baby stops feeding when try to switch from breastfeeding to bottle-feeding. It is because the baby gets confused because of unfamiliarity and change in shape and size of the nipple. Moreover, sometimes the baby feels the resistance in milk flow which makes them get irritated.

This baby bottle nipple allows the baby to continue his natural feeding motion and stick to the sucking pattern.
