Coming to a stand-still

Addy has come up with a new therapy game. She calls it "Ready, Steady". She stands in her walker (which scares the tar out of me because the point of the game is to let go and just balance by herself) or in front of someone with their arms stretched out beside her. She psyches herself up by chanting "Ready... Steady... Balance!" and lets go and stands still, just balancing herself. I counted a couple of times as high as 15 seconds before she had to grab on to my arms!
