Prince George of Cambridge, Queen Elizabeth II’s grandson and Prince William and Kate Middleton’s eldest child, is the third in line to the British throne. However, there’s a very big secret that his parents have been keeping from him — he still doesn’t know that he will one day become king.

The reason for this secrecy is that Prince William and Kate Middleton want their son to have a normal upbringing as much as possible. “I love my children in the same way any father does, and I hope George loves me the same any son does to his father. We are very normal in that sense,” the Duke of Cambridge told BBC in 2016.

Of course, a time will eventually arrive when Prince George has to know, but his loving parents are trying to delay that moment as much as they can. “There will be a time and a place to bring George up and understand how he fits in, in the world,” Prince William added. “But right now it's just a case of keeping a secure, stable environment around him and showing as much love as I can as a father.

It is interesting to note that the Cambridges’ parenting style is similar to the way Princess Diana brought up Prince William and Prince Harry. In an effort to provide a normal upbringing for her kids as much as possible, she enrolled William in a London nursery school. The young prince made history as the first royal family member to get his preschool education outside the palace.

However, William and Kate’s secrecy might not be sufficient to shield Prince George from learning of his future role. It’s highly likely that some children at his school might have already told him about it.

Also, there’s always that possibility that he will eventually figure it out on his own. “It will be, nevertheless, part of his upbringing both in terms of what he sees his parents and grandparents doing and probably quite soon a beginning of an understanding that he is in public life and what that means,” writer Catherine Mayer said.

Recently, an article from Pinkvilla claimed that Prince William and Kate might already be preparing to spill the beans to the young Prince George. However, they plan to do it in such a way that it would be simple and fun for their child.

“He’ll explain things as if he’s reading from a children’s storybook. So it’s fun for George,” an unnamed palace insider said.
