The author discusses the markedly exaggerated seductive behavior and insatiable curiosity about genitals in a three-and-a-half-year-old girl who was seen for ten hours. These symptoms reflected 'extreme castration anxiety and penis envy', but they were also relatively thinly disguised expressions of severe separation anxiety connected with repeated hospitalizations and separation from mother during the second year of life, traumatic weaning experiences, etc. Levin's patient once again illustrates the evolution of anxiety from fear of loss of the object, to loss of the object's love, to castration anxiety and fear of loss of the love of the internal objects.
