This paper is based on material from an analysis with a girl who was four years old at the time she started analysis. I relate how we worked with her feeling of vacillating, between invading and being invaded by the object, and how she was finally able to let go of her omnipotent control to a higher degree than before. Inspired by Hanna Segal and Donald Winnicott, I trace our progress from: (1) a denial of separation: (2) the analysand establishes a certain sense of separation by creating her own “space”. Through splitting and projective identification, she rids herself of feeling dependent and helpless, feelings that she cannot bear to acknowledge. The analyst receives, contains and names these feelings: to a stage where (3) the relationship established through the agency of projective identification is dissolved, and makes way for an ability to experience dependence as well as a recognition of the analyst as a separate person whom the analysand needs and can use.
