Help! My daughter has learned the finer art of using her sippy cup as an indoor milk sprinkler. Every time I turn around, she's spreading it over her carseat, her legs, her clothes, the couch, the floor, etc. etc.She's still pretty young, so the harder spout sippy cups are a bit much for her to handle. And I hear that the straw sippy cups require one to be able to bite and suck at the same time. Is that true with all of them?
Anyone have any suggestions of sippy cups that really are leak proof?
