I know others will suggest this, but in my opinion Dr. William Sears really has the greatest things to say about fathers' roles in his books. In "Nighttime Parenting" Chap 9 is "Nighttime Fathering" and is excellent. I know he has written other books as well, I am sure someone will name them. The best fed babies are breastfed babies!
