Sleep is a skill

I was pleasently surprised to come across this Child-Works, a sleep consulting firm. Here is a little bit about its sleep philosphy:

This philosophy is based on the notion that learning to sleep is a skill, just like talking, sitting up and walking. Sleeping well is a family issue and we believe that the child is not the soul focus of the sleep problems.

They have a lot of links, articles and books they recomend for parents that are trying to teach that life long skill of going to bed.
