She Brought Her Kids Everywhere
Royal children don't often accompany their parents on their work and leisure trips, especially out if the country if they were very young, but Diana wouldn't leave William and Harry behind. She wanted a genuine relationship with them, and most importantly, she wanted them to just be normal kids.
Her Boys Lived a Normal Life
William and Harry lived as normal a life as they could. Yes, they attended a ritzy public school, but they still did totally average kid things like eat at McDonald's and ride public transportation. They loved playing outside and riding their bikes. At amusement parks, they waited in line like everyone else. Diana did her best to make sure her boys were grounded.
