"Dr Spot's Casebooks" is a series of simple stories for children aged 4-7. Each story is about a different animal character (for example Franklin, the Frog or Charlie, the Cheetah) and deals with a different medical or behavioural condition, for example measles or ADHD (Attention Deficit Hyperactivity Disorder). In the books, Dr Spot the leopard doctor describes each condition in the context of the story and shows how it can be treated or handled. The stories are intended to be informative and reassuring, not only for children but also for parents/carers, for whom special parents' pages are included at the back of the books. These pages contain full information on symptoms, causes and action to be taken, including when to call in a doctor. In "Harriet, the Hippopotamus", Harriet has a nasty case of tonsillitis - just when she's supposed to be enjoying herself at her best friend's birthday party. Luckily, Doctor Spot is on hand to diagnose the problem and help her feel better.
