Agreed. We've used the "let them cry it out with increasing times between consoling visits" for all 4 of our kids and they hardly have any of the symptoms the author claims.

This is the kind of science I love: figuring out what's right for everyone by looking at averages.

Babies have different kinds of cries and parents have different needs. I'll say for myself and my wife that letting them cry it out seemed to help them learn to sleep alone in a far shorter time than any of our peers' kids. Sure, maybe our kids are different, but when I see the kind of entitlement parenting that often goes with the "cater to every cry" method, I'm less and less astonished at the self-centered attitude of the modern teen.
