"Understanding Your Child" is a parents' guide to the development and behaviour of children from birth to five years. A general introduction to the ideas and concepts of child psychology is followed by chapters on specific topics such as aggression, shyness, step-parenting, language development, discipline etc. At the end of the book is a development checklist which tells you what your child should be able to do at three months, nine months etc. The emphasis is on practical steps that parents can take to avoid problems with the emotional and intellectual development of their children. Dr Woolfson writes regularly for "Nursery World" and other magazines on child development. The book should also be of interest to nursery school teachers, paediatric nurses and child care workers.
