While much writing has been devoted, predominantly by contemporary Kleinian adult psychoanalysts, to the Kleinian and post Kleinian development of Klein’s work, comparatively little has recently been written about the ongoing importance and character of Klein’s clinical work for contemporary psychoanalytic psychotherapy or analysis with very small children (2 - 6 year olds). Little attention now seems to be paid to the revolutionary character of her work from the start (in the early 1920s) with this age group and its challenges, still relevant today, or to her recognition of the importance of mother-infant relations in the period long before World War II brought investigation into and understanding of problems of attachment, separation and loss. This book addresses these issues and re-explores Klein’s work in these (and other) areas. This book is concerned primarily with Klein’s work with pre-latency children and aims to give these small children more of the voice today that Melanie Klein herself discovered.
