Charlie Cheetah should be the fastest runner in the school, but when he runs races, he coughs hard and has a tight chest. His mum takes him to Doctor Spot, who diagnoses asthma and explains in simple terms what it is. Charlie is given two inhalers and shown how to use a spacer, and after that he's much better. The simple, brightly coloured illustrations of animals help make the story memorable, and there are two pages of detailed information for parents at the end of the book. An excellent series, recommended by The Patients Association and the National Asthma Campaign.
