Max's favorite new game is to lie in his activity gym and kick. When I set him up correctly, a bulls-eye kick does two things: it activates the shake sensor on the music to advance to the next track, and it shakes the rattle above his head. I was getting some pretty big smiles, which prompted me to take this video, but Max just had one big smile left for the video camera. It happens fifteen seconds in. After that he does lots more kicking, but he's more taciturn.
