Idk, I can just imagine him playing around with the boy, teaching him how to pick up girls, how to play football, stuff like that.

(Kinda like in the episode where he sees his ex with the kid).

However, you could do like a comedy if you had a girl. Like him punching his daughter's first boyfriend. That stuff would be hilarious. Anyways, I still stick with boy.

And LMAO! When I first saw the "Dean is goin to have a baby" I thought you meant like he would be pregnant. haha. I'm obv tired!

I think a little baby girl would be sooo cute. I've read one, once, where Dean got two girls, (twins), and it was so cute, and Dean was the perfect, protective father.
But of course a boy would be cute too, Dean would be an awesome father anyway:), a girl was just the first that came to my mind.

a girl! :D daddy!Dean with a baby girl would be totally and completely adorable :)

a girl , love him with a little baby girl!
he would protect his little girl and brooke so much =D !
I love brean [+baby] make some videos about them [:
