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. Steinberg discusses topics as varied as whether and how you should be involved in your child’s college education, how to behave when they unexpectedly must move back home, how to state your opinion on their romantic partners, what to do when you disagree with the way they are raising their own child, and what parameters to apply if you want to give them money for a home or startup.
