Prince Charles didn’t agree with Princess Diana’s parenting style.

According to the 2017 Amazon Prime documentary “Diana: The Woman Inside,” the Princess of Wales tried to keep things normal for Prince William and Prince Harry. For instance, she would take her kids to school and would be there when they arrived home in the afternoon.

She also took them to London Underground and on buses and taxis. One time, the bus driver was reportedly surprised when he saw his royal passengers. However, this did not sit well with Prince Charles, who believed that it was not necessary for their sons to experience those things.

“The Prince of Wales had a problem with this,” Ken Wharfe said.

At one point, Prince Charles reportedly asked Princess Diana why she made their kids ride a bus. He also confronted the late Princess of Wales for taking Prince William and Prince Harry to a burger bar when they have a good chef in the palace.

According to royal chef Darren McGrady, there was a time when Princess Diana told Prince Charles to cancel their lunch because she would take Prince William and Prince Harry to McDonald’s. McGrady said he told the royal mom that he could cook burgers for them, but the Princess of Wales insisted.

Princess Diana explained that what her sons wanted was the toys. The chef added that even if Prince William and Prince Harry were royal princes they enjoyed regular American foods and this was what Princess Diana wanted for them.

According to Paul Burrell, Princess Diana, Prince William and Prince Harry used to spend their Saturday night eating McDonald’s Big Mac and fries while watching “Blind Date” on TV. The trio would squat on a massive sitting room and would cheer on the contestants.

Wharfe revealed on Yahoo News’ “Royal Box” how Princess Diana wanted Prince William and Prince Harry to grow up like normal kids.

“They're no different from any other child. Diana was always keen to bring some normality,” Wharfe said.

Unfortunately, Princess Diana didn’t get what she wanted. Wharfe explained that marrying the royal family and enjoying luxury holidays, specialized travels and many others are not at all normal.
