King Charles regrets not being stricter in his approach to parenting while raising two sons, Prince Harry and Prince William, alongside the late Princess Diana.

Royal author Ingrid Seward claimed the 75-year-old monarch allowed for the former Princess of Wales to raise their kids without any boundaries.

Prince Harry and King Charles were very, very close,” Seward told Fox News Digital. “They got on incredibly well. I think Charles probably regrets that he wasn’t strict with Harry and [his older son] William.”

“He went on with [Princess] Diana’s freestyle of bringing up children,” the My Mother and I author explained. “Diana allowed them to do, more or less, what they wanted, which was very fashionable in those days. You let children just get on with things.

“I think Charles probably regrets that he wasn’t a bit stricter, because it might’ve given both boys a few more boundaries.”

“… Children all need boundaries, and I don’t think they had too many,” Seward added.

Despite his reservations towards his younger son, the King can’t help but love and miss him as he continues to make his life miles away

What’s sad for him is that he doesn’t see his grandchildren and that Harry has been such a disruptive force to the whole royal family,” the royal expert said of Charles..
