Chase and Halle play like that all the time until their little tongues are hanging out. They run into things, bump their heads, slide across the floor. There is no stopping the fun they are having with each other. At first I was nervous with the head bumping the walls or hardwood floor, but they never seem phased by it at all. Now I just let them have fun until they are all tuckered out. I love it. I keep saying I'm going to video it, but I haven't done it yet. It can be very entertaining.
