Dealing with children who have serious behavioural problems is always difficult, and the range of possible educational measures is limited. It always seems to come down to two choices: being too strict or too lenient. You no longer know what to do. You, the child and other adults are stuck in a frustrating and fruitless pattern of communication. The result is anger, powerlessness and disappointment. This is a manual that parents, teachers and childcare workers can use "on the shop floor". The emphasis is not on explaining what is happening, but on how to deal with what is happening. You learn how to use a system that works for both younger and older children. You become the child's trainer. From the foreword by Russell A. Barkley, Clinical Professor of Psychiatry and Pediatrics Medical University of South Carolina: My compliments to Dr. Noordzij for writing this smart, sensible, scientifically-grounded, and effective program for helping parents to manage their defiant child.
