Queen Elizabeth II was reportedly worried about her eldest son Prince Charles’ disruptive behavior during her coronation.

In “Charles, Prince of Wales,” author Anthony Holden described how 6-year-old Prince Charles was acting very fidgety just before his mom was crowned. The Queen was reluctant about putting her son to such an ordeal because it was the first time that a sovereign with an heir so young was to be crowned.

Holden said that Her Majesty was aware why Prince Charles was having a worrying behavior and wasn’t pleased because it might stretch her own taut nerves. As a result, the Queen ignored her son during the important milestone.

The book, which was published in 1979, revealed that the incident took place at Sandringham and Balmoral. Prince Charles had to be taken out of the parish church for fidgeting during the sermon. And two days before Prince Charles’ birthday, the Queen accompanied Prince Charles on his first public appearance. But the future King appeared to be so bored that he was taken home.

Prince Charles was allegedly spared the solemn oath of allegiance and a decision on whether he would be part of his mom’s coronation had to be postponed. Prince Charles’ name also did not appear in the official coronation program because the Queen had thought it would be best to just leave him at home.

But according to Holden, a young Prince Charles begged his mom to allow him to tag along, and this move softened the monarch’s heart. And while there, Prince Charles was surprised to see his mom surrounded by a large group of men in extravagant uniforms preparing to anoint her hands, breast, and head with oil.

Before the ceremony, the Queen gave Prince Charles a reassuring little smile to calm him down. And only one during the entire ceremony was Prince Charles seen misbehaving. Queen Mother restrained him from leaning over the balcony to get a better view of the coronation.
