This is a pioneering study, showing that it is possible to establish a dialogue with a psychotic child, and that schizophrenia in small children is treatable. There are few blow-by-blow analyses of psychotic children, and Sammy literally insisted that McDougall write during sessions, and hit her if she stopped. D.W.Winnicott provides a preface and it is thanks to his admiration for this study that it was translated into English.
