The Tilted-Head Breastfeeding Simulation Growth Bottle Series is designed to provide a seamless transition for babies aged 0 to 12 months while preventing tooth decay. Newborns’ underdeveloped gastrointestinal systems can lead to issues such as gas, abdominal pain, restless sleep, and vomiting. This anti-gas bottle is ergonomically streamlined for easy grip, and its tilted nipple mimics the breastfeeding experience, providing comfort and security to the baby. An anti-gas vent separates air bubbles from the milk, preventing them from being ingested by the baby, and a round-mouth, square-bottom design allows for faster milk dissolution and reduced spillage.
