This book contains a great program for teaching young children with autism how to interpret facial expressions and other social cues. It is aimed at young children. If you have a teenager with autism, you may need more help, since the typical teen's social environment is much more complex than that of a younger child. This of course begs the question of why anyone would wait until their child was a teenager to start addressing his/her autism. One should instead start as early as possible, preferably well before 3 years of age, and definitely before 5 years of age. The longer you wait, the more difficult it gets, and the less promising the prognosis. Is this book the only resource you will need to address your child's autism? Most definitely not! You should read "Let Me Hear Your Voice" by Catherine Maurice, and you should find a parent support group near you (check [...] for a list by region). ABA treatment is a must, and some children also benefit from changes in diet, megavitamin therapy, and other treatments. ABA (especially), diet, and vitamins helped several children in my community go from a diagnosis of autism to testing in the normal range. But they all started very aggressive treatment early: before the age of 4. So, read this book, but also gather information in the area of ABA, diet, and vitamins. Find other parents who are aggressively addressing their child's autism--you will need the mutual support. Above all, hit your child's autism with everything you can as early as you possibly can! There is not yet a guaranteed cure, but you can give your child a fighting chance of attaining a normal level of functioning.
