Query: a tired rehash of stuff you've heard before

Raising Cain is a tired rehash of child-rearing advice you've heard a million times. It's too bad that parents who are willing to spend moneyand, say, six hours of reading time to learn more about their sons will be so poorly rewarded. My advice: spend that six hours with your boys, doing something fun. Save the money for pizza and ice cream.
