The Munchkin 360 Miracle Training Cup is perfect for toddlers learning to drink from big cups. The innovative design prevents leaks and spillages, ensuring they leave no mess behind. The clever one way valve on the Munchkin 360 Miracle Training Cup cup allows your toddler to drink from any side of the cup just like a normal cup, however it only allows fluid to flow when your little one sucks on the valve. Drinking from anywhere around the rim, like a regular cup, helps support normal muscle development in a child’s mouth. And with no extra spouts, straws or pieces, the Miracle 360° Cup is easy to use and even easier to clean.
