A French-language professional work on the use of sophrology in pediatric psychiatric practice. The book considers how relaxation-based techniques may support children and adolescents experiencing emotional, behavioral, or psychological difficulties, with attention to clinical settings and therapeutic care. Intended for practitioners and students in mental health, medicine, psychology, and related fields, it presents sophrology as a complementary method that can help young patients develop body awareness, regulate stress, and participate more actively in their treatment. The focus is practical and clinical rather than purely theoretical, situating the method within child psychiatry and broader approaches to pediatric well-being.
