The Comotomo Soft Hygienic Silicone Natural Feel Baby Feeding Bottle Pink/White is designed to closely mimic natural breastfeeding with its innovative, logical design. The naturally shaped nipples are made of soft silicone, perfect for babies having difficulty transitioning from breast to bottle feeding. Your little one will love holding onto its soft, skin-like body, making it stand out from other bottles on the market. The wide neck design allows for brush-free, stress-free cleaning, while the dual anti-colic vents prevent colic and eliminate leaks. This bottle is truly one of the most thoughtful options available. Its squeezable, skin-like softness is ideal for breastfed babies, and the leak-proof, anti-colic vents with a unique interlocking feature and drip-free, wide neck design make cleaning a breeze. The Comotomo Natural Feel Baby Feeding Bottle Green/White can be safely used in microwaves, with boiled water, in dishwashers, and in sterilizers.
