Toby and his identical twin brother Booh were adopted when they were tiny babies. They look so alike that sometimes people can’t tell them apart. But there is one very big difference between them. Booh is always getting into trouble: upsetting other children, fidgeting in class and losing his temper. And as he gets older his behaviour just seems to get worse. What is wrong with Booh? This story about ADHD will be helpful for any child aged seven to 11 who finds it difficult to stay still or pay attention or whose behaviour frequently gets them into trouble. It will be equally useful for a child who knows someone with ADHD. This short booklet for children is part of a series designed to teach children about a range of health conditions common to many looked after children. The book includes a question and answer section which covers a wide range of queries and concerns about ADHD, and provides practical information and advice in a straightforward and child-friendly style.
