boy, girl, or hiding?

tomorrow we'll take our first peek at the new baby. I have this fear that s/he'll be hiding. but I'm guessing that it's a boy, as the pregnancy has gone a lot like Caleb's. we're both excited about the possibility of a girl, but having 2 boys of similar age would be really cool (if not completely insane for a while). so I'm going a little crazy with anticipation.
