I'm guessing boy, if it is his first.
Can't explain the feeling when you know you are having a baby boy...it is relief, excitement, pride and trepedation all rolled into one.
I am about to have a baby girl and have been told by fathers of daughters that a very special bond develops with fathers and their little girls (no..not that type, for all those sick minded of you out there)...but I just can't imagine a stronger bond than I have with my boys right now.
Sometimes I just grab them and want to sqeeze them so hard, but can't because it will hurt them.

We'll see.
But don't keep us guessing man...what is it..girl or boy?
