If a grownup you love has bipolar disorder, what does that mean? In this friendly guide, 11-year-old Josh tells all about his dad's bipolar, including what mental illness is, and how it can affect patients and their families. The guide explains in child-friendly terms how different types of bipolar affect people's feelings and behaviour. It is a comforting book that prepares young readers for the hard parts of knowing someone with bipolar, while communicating that bipolar is nothing to be afraid or ashamed of. Providing an excellent starting point for discussion both at home and in the classroom, it also includes a helpful list of recommended sources for additional support.
