When Prince George was born five years ago, a huge responsibility was instantly bestowed upon him in terms of the future role he will play in the British monarch.

But while he is third in line to the throne, his parents Prince William and Duchess Kate – conscious of giving their children as normal an upbringing as possible – are doing everything in their power to keep the information that George may one day be king hidden from their first-born as best they can.

Father-of-three William has spoken candidly many times about his family life behind closed palace doors, saying, “We are very normal.”

The future king also said in a previous interview, "There'll be a time and a place to bring George up and understand how he fits in in the world.”

As much as they call Buckingham Palace home, the Duke of Cambridge has stressed the importance he and Kate place on their children Prince George, Princess Charlotte and Prince Louis spending their childhood growing up in a “real, living environment” and not constantly “behind palace walls”.

It was documented in 2015 book Charles: The Heart of a King that Prince William struggled during his youth with coming to terms of the future role he inherited as second in line to the throne.

Author Catherine Meyer, who wrote the tome, told E! News in 2015, “With George they are trying to delay that moment of realisation and give him normality before they thrust this on him.”

She added, “But 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.”
