"The migration process is impeded by different challenges. Refugees must deal with their own traumatic experiences, which are intimate and personal but also relate to collective trauma that can destroy a sense of belonging to a community and weaken shared values. In addition to multiple traumas experienced in their country, refugees face the trauma of migration itself and the dramatic events that occur during migration. We argue that every migration process constitutes a traumatic experience marked by a rupture with the country of origin, by the modification of relational links, and by difficulties in cultural identification. In these situations, the parent-child relationship might be severely compromised. Children in migration are exposed to a particular vulnerability described by the concept of “exposed child”. We address the sequelae of the disruption of cultural meaning systems and cultural belonging invoked by collective violence and by migration itself, focusing on a specific therapeutic device for families. We illustrate the theoretical elaboration of this device with a clinical vignette."
