Mariella and her guests ask what parents can do to help children with mental health problems and what constitutes a 'normal' level of unhappiness in childhood and adolescence. She hears from a mother who fears her unhappy 11-year-old-son will go off the rails in adolescence and a mother and daughter on the drawbacks and benefits of having a mental health diagnosis. With guests the family therapist Jan Parker, Richard Reeves of the thinktank Demos and Roger Catchpole of YoungMinds.
