Our service offers a space dedicated to the accompaniment of children and their families in which we propose to live a common activity around a device: psychomotor and climbing sessions. These activities facilitate the meeting and allow children and their families to share a moment of play and fun. Two social workers trained in relational psychomotricity supervise and accompany the children and their parent in session. This relationship approach fosters a relationship of trust and helps to formulate requests relating to the child’s social environment. Social and educational prevention activities for the benefit of children are thus developed.
