In nursery schools in the Paris suburbs, the extra-familial mutism of migrant children appears to be over-represented. By inviting a young mute boy and his parents from Chechnya to draw their transcultural genogram within the school, we were able to understand the place of school, family and language. With the desire to welcome this family into the institution, this drawing of origins seems to have the capacity to weave and reassure bonds of attachment, enabling us to maintain contact with the familiar and venture into the unknown.
