Donald W. Winnicott is one of the first psychoanalysts to recognize and investigate the significance of the real mother-child relationship for psychological development. His formulation of the "good enough mother," meaning a mother who is not ideal but still "good enough" to allow her child to develop healthily, has become famous. With his provocative statement that there is no baby, only the baby in unity with the mother, he has led us to insight into the eminently social nature of human beings. Winnicott's unusual ability to see deeply into the human soul with creative intuition and to communicate this in simple words makes the book interesting not only for child and adult psychotherapists but also for anyone who works with children or with childlike ideas or behaviors.
