This paper describes the behaviour in analysis of a 2½-year-old psychotic girl whose pathology seems to date back to her pre-natal life and traumatic birth. It describes how she seems constantly to be reliving her past life inside the womb, trying to re-create it through various means. This, as well as providing her with a source of seemingly endless sensuous pleasure, seems to protect her from very strong feelings of jealousy of a very primitive kind and from having to re-experience her traumatic birth. A particular emphasis is given to her complicated and often strongly eroticized relationship with her umbilical cord. Some consequences of her regressive state are also described. The paper concludes with some questions and hypotheses on the origins of this kind of pathology in this particular child.
