Miniware Sippy Cup for Babies is the only true training cup which helps a child advance all the way from a straw to mastering a real cup. It enables a child to transition from sipping through silicon straw, which is soft and feels good against gums and teeth, to practicing drinking from lid + spout and finally mastering a real cup on their own. It’s made with 100% natural plant based ingredient which not only guarantees your baby’s well-being, but also protects the environment.
