Now that we are raising two grade school age grandsons, we are finding out that boys are different from girls. There developmental process is much different than was our daughters'. So we recently checked out a copy of Dobson's book, Bringing Up Boys from the library. It was well worth the time.
Dobson points out several elements of distinction between the development of the genders. We believe we were benefitted in the confirmation of many things we are doing for the boys, and given some new ideas that we want to incorporate for the benefit of the guys. If you are raising little boys, you should give this volume a look.
