A.,
I suggest you guys talk about this. My husband was scared to death that he would never get to do anything fun again as soon as we had a baby and did all kinds of strange things because he thought he had to cram it all in. We did some counseling around it and it got better and now he loves being a dad etc. I think it will only get worse though if you don't deal with it now. As much as he imagines he might have to "grow up" when he has his own child, some of those new parent responsibilities do seem overwhelming at first and if he's already scared, he might really freak out. Good luck.
