William and Kate, the Duke and Duchess of Cambridge, are setting trends for millions of parents around the world. The upbringing of their children, Prince George and Princess Charlotte, is the focus of intense popular scrutiny. Royalty have always raised their children in the public eye and attracted praise or criticism according to parenting standards of their day. Royal parents have faced unique challenges and held unique privileges. In medieval times, raising an heir often meant raising a rival, and monarchs sometimes faced their grown children on the battlefield. Conversely, kings and queens who lost their thrones in wars or popular revolutions often found solace in time spent with their children. In modern times, royal duties and overseas tours have often separated young princes and princesses from their parents, a circumstance that is slowly changing with the current generation of royalty.
