Prince William and Princess Kate have had one united mission for the last thirteen years: to give their three children, Prince George, Princess Charlotte, and Prince Louis, as normal a childhood as possible. That is the resounding explanation as they prioritize soccer games and school runs over royal duties, at least while they can. This is a huge shift from royal childhoods throughout history, where the future monarch was brought up from an early age in a world of nannies and tutors behind palace walls.
