Kate, the Princess of Wales and Prince William have prioritised raising their children as “normal” as they can while they grow up within the Royal Family, but they can’t act in exactly the same way as their public peers.

Given their likely futures as working royals, Prince George and his siblings, Prince Louis and Princess Charlotte, still receive strict instruction. The children, aged 10, eight and five, are all in primary school, with the eldest sibling having returned to Lambrook this week, and must follow rules laid down by their mother.

Insiders have revealed a selection of ways in which the Wales family’s lives may differ from youngsters in the general public. They have touched on seven imposed by the future King and Queen, ranging from a not entirely unusual iPad ban to a strict fast food-free diet.

Among the food rules reportedly in the Wales household is a ban on fast food. Darren McGrady, the former chef to the late Queen Elizabeth II, once told Today he had never seen any of the royal babies eat packaged food.

He said he had “certainly never seen packaged food with any of the royal babies”. He questioned why it would ever be necessary to buy packaged food when the royals have “20 personal chefs”.
