Lately Aidan has been pretty interested in his anatomy — namely the part of his body that makes him different from a girl.  A couple of days ago, while William was getting him dressed for Montessori, he had the following conversation with his dad:

Daddy, I am a boy.  I have a pee-pee. 
(He stops and thinks for a little while.) 
Today is Show-and-Share day in school.

Oh boy!  Wonder where he was going with that last thought.  🙂
