"A much-needed guide for parents of people in their twenties and thirties from one of the world's leading developmental psychologists. Your child is now an adult, but your job as a parent is far from over. Instead, your role must evolve to meet their ongoing, changing needs. But what exactly are these new needs? And why are they so different now than they were when you were a young adult? This is the first comprehensive guide written for parents whose children are in two of the most crucial decades of life"-- Provided by publisher.
