Your husbands comment about sewing her up is really odd and concerning, as is the rest of his behavior. This is his daughter, a human being, and he's relegated her to nothing more than body parts. He sounds like he has EGD. You need to talk to him about getting counseling.
I'm sorry no one is happy for you. Two little girls sounds really wonderful to me. A good friend of mine has 3 girls but the youngest two are really close in age and they're best friends. It's the sweetest thing ever.
