With respect to a gift from your son, give Daddy something that they can play with together later, like a baseball mitt and ball sized for both, or something to that effect. I gave my husband gifts like that from our first child and he loved them (framed photo of the two of them is also a good one). Also, anything that suggests alone time for the two of you (without baby) would probably be appreciated. Not necessarily something sexy (although that NEVER hurts!), but even movie tickets, dinner reservations, a bottle of wine or some such. As a SAHM anything that says "I'm getting you out of the house" is a great gift! I don't know what your husband is like but I know mine loves this place down by the Perimeter called Roosters, it's basically a fancy barbershop/spa for men where they give them free beer and sports tv and WiFi while they are waiting for whatever their appointment entails (haircuts, shaves, "man"-icures haha, whatever). I know some guys think they are turning in their man card when they do this stuff but this place is just for guys and I figure your hubby would appreciate even just a nice hot shave at a place like this since he probably doesn't get out of the house much without the baby.
