The sippy cup has a removable clear top that can be set aside when it is time to transition to a toddler mug.

 Not only does it come in a pattern that mama will enjoy, the top is easy and fast to push onto the mug and stays sealed! This cup has been tested for over a year at home, and despite many dishwasher cycles, the cup's seal has stayed perfectly tight, no leaking except through the small drinking holes where liquid should come out. The design will withstand the dishwasher and stay bright and cheery too!
