Be Prepared: A Practical Handbook for New Dads by Gary Greenberg and Jeannie Hayden. I gave it to my dh to tell him I was pregnant. Its quite funny, but very informative too, supportive of breastfeeding, etc. Its not what you would call "crunchy," but its still good. Dh really liked it, so much so that he gave it to one of our friends who is expecting his first child in June.
