Less reflux means less fussing and more enjoyable feedings for parents and babies. Dr. Talbot's Anti-Colic Bottles have a venting system that draws air to the base of the bottle, helping to reduce colic symptoms like wind, reflux, and fussing. This baby bottle also features a Soft Flex Simple Latch Nipple designed to mimic mom's nipple and encourage latch-on. Plus, internal ridges prevent the nipple from collapsing while your baby is feeding. When feeding time is over, sterilization is easy and convenient. The bottle's multi-part venting system can be fully removed for thorough cleaning, and the bottle's self-sterilizing system uses only the bottle's components, water, and a microwave. Made from BPA-free materials for parents' peace of mind, Dr. Talbot's Anti-Colic Bottles come in a two-pack, so parents will always have a clean bottle at home or on the go!
