A small child's clinic is a place of many questions, especially as regards the intervention of the psychoanalyst. In order to analyze issues considered crucial in contributing to this clinic we chose to analyze a clinical case recognized, "If Nadia or mirror" of the psychoanalyst Rosine Lefort. We seek to use the case as a guide for discussion of the psychoanalytic act, the role of agent-feeding, early intervention, trying to locate the position of the analyst in dealing with children still in the process of formation. We try to distinguish the position of the psychoanalyst an assemblage of the maternal role, highlighting the points where these positions converge or differ.
