That is so cute! Sounds like she's doing pretty good and that's great.
Kacee and I played a little game on the hard floors yesterday. You might try it. I just sat on the floor and she was somewhat lazy and just stayed there between my legs. I got a plastic pop bottle cap and I'd toss it in the air a little bit and she'd pick it up and throw it with her mouth. This went on for, oh, I'd say a good twenty minutes, maybe!
