The infantile updated in transference configures tangible limits to the knowledge of the psychoanalyst. In the primordia of Freudian experience, when the child represented the repressed sexual, interpretation configured the maximum expression of this knowledge. With the perception of the limits of interpretation, evidenced by the formulation of the concept of working through (Dürcharbeitung), there was a displacement, in Freudian praxis, of interpretative knowledge to sheltering of the regression of analysands and to shared playing. Since then, the figure of the traumatized child would play the leading role in the scene, which was evidenced by the clinical style developed by Ferenczi and Winnicott.
