Be glad that he is wrapped up in your son!!! Many dads aren't. They just come home from work and plunk their butts on the couch and watch tv with a beer.
Have you ever ASKED your husband to sit down with you and talk? Maybe he doesn't realize exactly how much he shuts you out. Don't be negative when you talk, always start with a compliment. Tell him that you love the fact that he is so loving and attenttive to your little boy, but you feel a bit left out. Then ask him if you can schedule some time in for just the two of you. Even some cuddle time on the couch after your little one is in bed.
