I feel badly that no on replied - I think this thread went around a few months back, so check the archives of this forum.
My only comment is that I just skip over the parts of books that don't apply - sometimes, you can run into this "mommy is the primary caretaker, daddy is the helper" kind of belief, especially about parenting babies. (Aside from the fact that there are TWO mommies in our family, my partner and I don't operate that way at all. We are very equal parents in every way. I know some lesbian families do have one parent who is more "primary" though.)
