Stand Up Cups are great for children just starting to learn to drink on their own, but who are still a tiny bit wobbly and uncertain when it comes to putting their cup back up-right on the table. This sippy cup has a roly-poly bottom with a weight in the base, which allows the cup to right itself up if It's put down crookedly. It simply can't tip over! The cup's handles are nice and big and easy to hold. To assist your child in learning to drink on their own, the cup comes not only with a mouthpiece, but also with an additional drinking lid piece, for the second stage of drinking.
