With its unique design to be as familiar to baby as mom's breast, our extra soft high-grade silicone nipples provide the perfect solution for switching between breast and bottle. For a more natural feeding experience, different flow rate nipples are available to mimic mom's nipple changes during nursing. Additionally, the built-in anti-colic vent system prevents common issues of colic, gas and reflux by eliminating air bubbles in milk for proper digestion.
