In this case study the author testifies about her encounter with an eleven year old boy who is resident in the treatment centre De Dauw. The crucial question is how to understand infantile psychosis. The author begins with difficulties experienced in the community and in individual psychotherapy. In order to bridge the gap between theory and practice, these difficulties will be explored and translated from within a psychoanalytic framework. The author considers the coming into being of the subject and the consequences in terms of drift and affect regulation, giving meaning and the relationship to the Other. Throughout the text, the author tries to shed light on the goal of treatment.
