In this study, the psychological structuring of a latency period boy who experienced delactation during the oedipal period was interpreted in the light of psychoanalytic theory using the Rorschach Test and CAT. The act of sucking itself has a source of pleasure beyond the satisfaction of the infant's stomach. When and how the delactation experienced will always remain important in making sense of psychological processes and will form a psychological blueprint for the child's future relationship designs. In this study, prolonged orality and leaving the child in a state of over-satisfaction make it difficult to process impulses and affect psychologically. The bombardment of sexual and aggressive impulses continues. In the light of the test findings, it is thought that incestuous intimacy with the mother and weak paternal functioning interfere with the development of the superego. It is thought that this difficulty in transitioning to the calm and impulsivityfree atmosphere of the latency period may be one of the reasons why the suppression of oedipal fantasies fails to take effect in the psychic apparatus. In this case, in which traces of childish sexuality were observed, a series of symptoms were tried to be made sense of in relation to parental attitudes and psychological structure.
