An INTRODUCING PRACTICAL GUIDE to how children think and grow. Child Psychology is a branch of developmental psychology, which is the scientific study of systematic psychological changes that occur in human beings over the course of their life span. Child psychologists examine how children’s brains work even before they are born, through to the beginning of adulthood. They may explore questions of how well children develop language, how they respond to other children and adults, how quickly children become aware of their environment and become autonomous from their parents. In this Practical Guide, child psychologist Kairen Cullen applies the lessons from a lifetime’s research and practice in the area to help you understand - without jargon or technical language - why your child develops in the way he or she does, and how you can best create the conditions for their living a healthy, successful and happy life.
