Our non-spill wide spout is fully manufactured in silicone and in only one piece which facilitates cleaning. We designed it to accompany your baby in the transition from the baby bottle to the baby cup. You can use it in any Babelito wide-mouth baby bottle. Available in one single size. They have an “air valve” system in their base that allows for the steady air entrance to the bottle, causing continuous output of food that reduces the risk of colic and hiccups.
