Prince George, Princess Charlotte and Prince Louis may not even be teenagers yet, but they are already very popular among royal fans. While they are most likely well aware of the significance of who they are and the family they are part of, Prince William and Princess Kate’s children live a fairly ordinary life at the moment.

Although they do step out on the royal stage a handful of times a year, with Trooping the Colour and the Christmas Day walkabout being the main example, they spend the rest of the time living a life not too dissimilar from other children. This involves going to school, taking part in sporting activities and enjoying quality family time at home.

However, while George, 12, Charlotte, 10, and Louis, seven, may have a fairly ordinary life away from the spotlight now, this won’t be the case forever, especially when they leave education.

This is especially true for George, who is second-in-line to the throne, who will have a more prominent role than his younger siblings.

However, with all three of William and Kate’s children expected to take on some royal role in the future, former royal butler Grant Harrold has shared when he thinks that will be.

While some royal fans are eagerly waiting to see George, Charlotte and Louis more, Mr Harrold – who worked for King Charles between 2004 and 2011 when he was the Prince of Wales – believes this won’t be the case for some time.

Instead, Mr Harrold thinks the children won’t become working royals until their twenties at the earliest.

Speaking on behalf of Study Dog, Mr Harrold said: “William is determined to give his children as normal a childhood as possible.

“He’s made it clear they won’t be expected to take on official royal engagements until well into their twenties, allowing them time to grow up out of the spotlight.

“While they’re gradually being introduced to royal events to help them understand the responsibilities that may come, there’s no pressure for them to take on significant roles any time soon, and perhaps not at all, if they choose a different path.

“Traditionally, royals were expected to serve in the military or undergo formal training, and while William may still encourage this for George as a future king, it’s unlikely to be forced. The approach is modern, flexible, and focused on their well-being above all.”
