When I first broke my ankle, Kaiden asked me if he could sign my cast (I think there was some prompting behind that question). I didn't have a cast the first four weeks, just a splint. Last Saturday was the first time since I've had the cast that we were able to have him sign.
He very carefully wrote his 'K' and then wanted to write something else, so he added Hi.
He was very proud of what he wrote and so was I.
