Having a boy is wonderful! You won't believe how awesome the bond is!
The 2 books I love, ironically, share the same title. One is a collection of "boy" stories from pregnancy through the teen years. It's called "It;s a Boy: Women writers on raising sons" This is one of those 'made me laugh, made me cry' types but not in the typical "Chicken Soup" way. Love it!! It's edited by Andrea J. Buchanan
The other is titled "It's a Boy: Understanding your son's development from birth through age 18" authored by Michael Thompson. This is a more 'nuts and bolts' book with a lot of information regarding the psychological and emotional differences between girls and boys and really does a good job explaining "typical" boy behavior.
Best of luck with your pregnancy!
