The British monarchy is known for its strict adherence to royal rules, and those high expectations extend to the royal children. Darren McGrady, the former royal chef who worked for the late Queen Elizabeth II and Princess Diana, told Harper's Bazaar that including Prince George, Princess Charlotte and Prince Louis Younger members of the royal family are not allowed to attend official dinners. their parents, including during the holidays until "they have learned the art of polite conversation."

Instead, the royal children had to have dinner in the nursery with their nanny. Maddie added: "The children always eat in the nursery until they are old enough to behave properly at the table." He also revealed that nannies play an important role in developing the royal children's palates.

“The Royal Nursery was about educating not only the minds of the young royals but also their palates,” Maddie recalled of his time working for the British royal family. “The nanny is always on top of the menu, making sure they eat well-balanced meals that not only include lots of healthy vegetables, but also introduces them to new adult dishes.”

McGrady also revealed in a previous interview with Bustle that Prince William and Prince Harry inherited their mother's love for sweets, especially banana pie and chocolate ice cream when they were young. "The boys were bananas and they loved bananas," he recalled. "William is very fond of chocolate biscuit cake, which is also a favorite of the Queen. We do it all the time at Buckingham Palace."
