Anti-colic baby bottle with complete internal ventilation system. Helps reduce colic, gas and regurgitation. The air does not mix with the milk and avoids the oxidation of the natural vitamins A, C and E of the milk. Reduces the risk of otitis media. Non-vacuum feeding similar to the maternal breast. Can be used with or without the ventilation system, ideal for growing with baby. Recommended age: *6-36 months.
