The Psycho-Analysis of Children, first published in 1932, is a classic in its subject, and revolutionised child analysis. Melanie Klein had already proved, by the special technique she devised, that she was a pioneer in that branch of analysis. She made possible the extension of psycho-analysis to the field of early childhood, and in this way not only made the treatment of young children possible but also threw new light on psychological development in childhood and on the roots of adult neuroses and psychoses.
Klein's ideas about children, along with her many innovations in adult therapy, placed her in the top ranks of a group of 20th-century psychoanalysts who pioneered the study of early childhood psychology
