I wanted to point you to a book on the same subject by psychologist John Gottman. He has written a number of family-relationship-parenting books and his latest is called "And Baby Makes Three."
What separates Gottman from all the other parenting advice crap is research. The Gottman Institute has studied thousands of families over extended periods of time in order to find what really works in marriage and child rearing. I know I sound like an ad for the guy, but his work is a breath of fresh air in an area filled with chatter and nonsense.
I haven't read the book myself, and y'all know I take most "expert" advice with a grain of salt, but this is a pretty strong endorsement from a fellow Parenthacker.
Has anyone else read this book? What did you think?
Update: I have since read a bunch of Gottman's books and I have to agree with Michael — his work is truly worthwhile. — Asha
