Query: Might as well be called "How to abuse your child"

Another book written by a man that claims mother's instinct does not exist. Any man who writes a book on childcare and does not back his word up with research (not a reference listed in the book), or ignores a woman's basic biological knowledge of her own child has no business writing a book on childcare. Thank God it's out of print.
