This book is for parents, teachers and caregivers of youngsters with autistic spectrum disorders. Written in plain English, it offers practical strategies for preventing or managing the sorts of challenging behaviour most likely to be encountered. With detailed case studies and key tips that allow it to be used as a quick reference, it also offers a step by step framework that enables readers to devise their own solutions. The book's core message can be summed up in a single phrase: to change a child's behaviour you need to be able to make sense of that behaviour - and making sense of that behaviour means making sense of his or her autism.
