I can't give this book 5 stars only because I personally didn't read it. I purchased this book and immediately gave it to my child's teacher. She read the book and passed it to the Guidance counselor. They both took teachings from this book and applied them to my child. With the fantastic support system from the school, my child has become increasingly verbal in the classroom setting-where he was completely silent last year. They both said this book helped them learn a lot about SM and how to apply techniques to my child.
