Puberty is an age of physical and mental evolution. Adolescents react with rebellion or depression, and relationships with them can often be tense and impassioned. Helpless parents often blame themselves, but they must remain in their parental position and control the adolescent. To try to solve these problems, the author answers questions such as: How to understand adolescent rebellion and aggressiveness? What is the specific position of the father and the mother? What lies behind the school problems? Excessive behaviour to be accepted? What is the best approach to adolescent sexuality? What is your response to a risky attitude? How limited are co-existence issues? How can we help the adolescent when he is unwell?Dr Patrick Delaroche, a child psychiatrist and psychoanalyst, and the author of Parents: How to Say No and ¿Psychologist or Non-psychologist? helps parents stay in position, stay alert without being intrusive, and to reconcile leniency and authority.
