This research examines the experiences of children in a Social Children's Home after school. Starting from the violence of placement, particularly in the travel which it imposes on the child and in the separation that he suffered, we make the hypothesis of an inherent violence to the fact that the placed child is forced to live with others in a new space and to spend their day with them: we call it violence of cohabitation. In the Children's Home indeed, children will meet other children who will have too, in their life courses, lived several kind of violence. Both victims children and teenagers share their every day life and the professionals who take care of them. This violence is thus both, in the fact that children are forced to live together in that confront their own life stories, but also in the cohabitation of these children in the psyche of the institutional, educational and school teams. This study shows that this violence of the cohabitation appears within the groups of children, and also in the institutional practices, particularly in the educational care of these children. From our clinical practice in the Children's Home, we observed a group of 11 children, from 4 to 10 years old, who were part of the same “group life”. We observe them for four months, from 4:30 pm to 7 pm. We used participating observation. Three categories of analysis were retained, while taking into account the reasons for the placement and the symptomatology of each of the young people: perception of child behavior at school by his teacher, the child's behavior in the Children's Home after school, and perception of the child by the educational team. For our analysis, we divided the group of children into two subgroups: those who have homework (n=8) and those who do not have homework (n=3). From the various analyzers selected, different themes and psychological representations were highlighted by the educational team. Concerning the children who do not have homework, the results show the importance of attention research from them to their teachers. These children are often considered as “agitated”, “unstable” or even “exhausting”. The educators also insist on the need to monitor them and offer them a therapeutic treatment. About the children who have homework, they are rather seen as children who make “efforts”, although they often have concentrating difficulties and they may not be free to do their homework. The results of this study show that children are in the research for a shoring educational, relational and emotional high from their teachers. Whether they have homework to do after school, these children try to be assured of a place in the psyche of the adults in charge of them. However, it appears that when these children have no homework to be done, learning activities can sometimes be shelved in the daily. A delegation, even unconscious, is then made of the school in the Children's Home and of this one in the other systems of care. Solicitations made for the educators can also generate a feeling of overflowing for these last ones, who find it difficult to receive an excess full of requests for attention from these children. Finally, we propose a discussion about practices of educational teams, in collaboration with other professionals in charge of the foster child in this fitting of the systems between schools, care institutions, family and society.
