S.,
A little about me - Married 38 years, mother of two, grandmother of three. Having been married 38 years, I've realized that Men ARE from Mars and Women ARE from Venus. We think differently about things. The fact that your husband is excited and going to every doctor's visit with you is awesome.
When our 32 year old daughter was born, my husband was hard pressed to be in the waiting room because he was terrified of hospitals. Your husband may be giving you as much as he is emotionally capable of right now just by going with you to the doctor. Remember, you've been through this twice. This is his first. Sometimes men want to learn stuff on their own, without admitting that they need to know it. My suggestion is this, try leaving the book in the bathroom. When he's having some alone time in there, he just might pick it up. If he doesn't, my experience is that when I try to force anything on my husband, he becomes more resistant.
When I have expectations that my husband is going to be as enthusiastic and interested in something as I am, and he isn't, I get let down. My expectations of others is what usually gets me in trouble. (I just had this conversation with my daughter yesterday.)
As far as the housework - let him complain. Don't take his complaints personal. He'll get over it!
Best of luck and congratulations,
L. W.
