Does your toddler stubbornly insist they can do everything themselves? That's wonderful! Because the more independent they are, the better and faster they develop. Our Mio trainer cup with a Miffy Explore motif helps your child to drink independently. Drinking from it is just like using a real glass, but the clever lid ensures that the liquid inside doesn't all come out at once. The trainer cup has a leakproof seal and can take a knock or two.
