Prince William Jokes Princess Diana Would Have Been A “Nightmare” Grandmother

Diana might have liked her grandchildren a little too much, he jokes. “She’d be a nightmare grandmother—absolute nightmare. She’d love the children to bits, but she’d be an absolute nightmare,” he says. “She’d come and go and she’d come in probably at bath time, cause an amazing amount of scene, bubbles everywhere, bathwater all over the place, and then leave.”

Though nearly two decades have passed, William still feels closely connected to Diana. “They always live with you, people you lose like that,” he says. “My mother lives with me every day.”

In the documentary, William and Prince Harry share never-before-seen family photos and open up about Diana’s life inside the palace walls. For the most part, the two brothers had a happy early childhood. In fact, William only ever remembers seeing his mom cry over stories in the media. “Harry and I lived through that, and one lesson I’ve learned is you never let [the media] in too far because it’s very difficult to get them back out again. You’ve got to maintain a barrier and a boundary,” William argues, “because if both sides cross it, a lot of pain can come from it.”
