The Chicco WB Glass Bottle is designed for babies 0+ months to alleviate colic, regurgitation, and irritability during feeding. It features a slow-flow silicone teat with an anti-colic valve for a smooth, natural feeding experience and easy transition from breast to bottle. Made from heat-resistant, thermal shock-resistant borosilicate glass, the bottle keeps liquids at the ideal temperature longer. It has a wide neck for easy cleaning, is dishwasher-safe, and suitable for sterilization. The anti-leakage cap ensures hygiene, and the bottle comes in colorful designs to enhance the feeding experience.
