Less reflux means less fussing and more enjoyable feedings for parents and babies. Dr. Talbot's Anti-Colic Bottles are designed with a venting system to help reduce colic symptoms and a self-sterilization system that uses only the bottle components, water, and a microwave. To meet your family's needs, Dr. Talbot's offers an array of replacement parts for our Anti-Colic Bottles. These replacement handles fit Dr. Talbot's 6 oz, 9 oz, and 11 oz Anti-Colic Bottles. Available in a convenient 2-pack, parents will always have back up at home or on the go!
