Why Mum? is a children's picture book exploring the serious illness of parent through the eyes of seven-year-old Matthew. It works chronologically through the illness and deals with the different feelings and questions the child experiences as they arise. It also shows how life changes for him and the family and how he adapts to this. Beautifully illustrated by the author's son, this book is about one mother's illness and her family's experience. It would be useful in any situation where a serious illness affects family life and especially where young children have to deal with difficult situations.
