We've been practicing Nolan's jumping jacks. He's getting better but still clams up during T-ball. I'm certain he's just nervous but perhaps it's forgetting how to do them. They are quite complicated when you think of it. When he crouches down and jumps into the air is another 'exercise' done at T-ball called a rocketship. Anyway, enjoy this. This video gives me as much joy as watching him learn/discover how to jump. Some day it will all come together but for now it's so fun to watch.
