The Munchkin 360 cup was the first sippy cup we tried with PJ. He loved having handles to hold on to & mimicking drinking out of a cup like his big sister. I love how it is pretty leak proof. It only leaks for a quick second upon making contact when hitting the ground. Much better than many other cups, which will leak the entire contents if they hit at the right angle. It also holds about 9oz & fits wonderfully in most diaper bag pockets.
