Child psychoanalysis is a sub-field of psychoanalysis which was founded by Anna Freud. Freud used the work of her father Sigmund Freud with certain modifications directed towards the needs of children. Since its inception, child psychoanalysis has grown into a well-known therapeutic technique for children and adolescents. History For many years, the work of Sigmund Freud was considered revolutionary in his creation of psychotherapy, or talk therapy, and his theories regarding childhood experiences affecting a person later in life. His legacy was continued by his daughter Anna Freud in her pursuit of psychotherapy and her fathers theories as applied to children and adolescents. In 1941, Anna help found the Hampstead Nursery in London and there she treated children for several years until it was shut down in 1945. Anna, with the help of Kate Friedlaender, soon opened the Hampstead Child Therapy Course and Clinic to continue her work and to continue sheltering homeless children. Anna was the director of the clinic from 1952 until her death in 1982. The clinic was renamed the Anna Freud Center following her death as a memorial for the care and support she provided to hundreds of children over the decades.

Some of her more famous books are "The Ego and Defense Mechanisms", which explored what defense mechanisms are and how they are used by adolescents, and "Normality and Pathology in Childhood" (1965), which directly summarizes her work at the Hampstead Clinic and other facilities. In fact, it was her work at the Nursery and the Clinic which allowed Anna to perfect her techniques and establish a therapy specifically designed for improving child and adolescent mental health. Techniques Anna's first task in developing a successful therapy for children was to take Sigmund's original theory regarding the psycho-social stages of development and create a timeline by which to grade normal growth and development. Using this line, a therapist would be able to observe a child and know whether they were progressing as other children or not. If a certain aspect of development lagged, such as personal hygiene or eating habits, the therapist could then assume that some trauma had occurred and could then address it directly through therapy. Once a child was in therapy, techniques had to continue to change. Foremost, Anna knew that she could not expect to create
