You can get the book at Amazon.com & any bookstore. He goes into the importance of sleep, what our bodies do at night & why it’s so important. He talks about the changes in the cortisol levels in our body at night, how we have that dip. It is basicly a very woren out book in my house. Everytime my oldest..NonCAH daughter stops sleeping through the night I pull out the book & I can find the answers pretty easily. My CAH daughter has no problems with sleeping...she gets that from me!Jessica K
