The sound of one hand clapping

When Kieran is excited, he opens and closes his hands, kind of like a one-handed clap. Mostly it's his right hand. He got really excited just now when I was walking toward him eating an apple. I think he thought he was going to get some. I think it might be a little bit early, even if I did spot a third tooth coming in last night (the right of the top middle two). Plus he doesn't especially like applesauce.
