If you are having any qualms about giving him a doll, check out the children's book "William's Doll" by Charlotte Zolotow. It's a really nice book about a little boy who has a dolly and he pretends he's it's daddy.

Go for it Sarah. He'll probably love it. And if you can't find a "boy" baby you like, you can always get a blue newborn pyjama and redress the doll. That's how we got boys at our house.
