The Munchkin Miracle 360 Trainer Cup prevent leaks and spillages and ensures there’s no mess when your toddler is learning to drink from their own big cup. The clever one way valve on the Munchkin Miracle 360 Trainer 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.
