In this chapter, I describe the development of a therapeutic relationship with a sexually abused latency girl who, in the course of her 2 years of four times weekly psychotherapy, was placed in two different foster homes. The child moved from an initial seductive relationship to her therapist to the use of the therapist as a new developmental object in order to establish a sense of basic trust. This was paralleled by the child’s development of a capacity to think and to tolerate affect states. The use of powerful counter-transference feelings in the therapist is seen as the main therapeutic tool in the treatment.
