Prince George, Princess Charlotte, and Prince Louis, the three children of the Prince and Princess of Wales, have the cutest nickname for their grandfather King Charles III.

Because of his former title as Prince of Wales, the young royals refer to their grandfather as “Grampa Wales.” We know the kids get to spend a lot of time with their adored grandfather because they live close to one another in central London.
King Charles is a doting grandfather
Prince Charles demonstrated what a loving grandfather he is while entertaining Prince Louis on his lap during one of his first significant public appearances at the Queen’s Platinum Jubilee pageant two years ago.

Queen Camilla, the wife of King Charles, is a stepgrandmother to Charles’ grandchildren as well as having her own grandchildren.

The royal said, “Well, what’s so lovely about being a grandmother, they teach you things and hopefully they learn a few things from us,” when discussing the significant role during a previous visit to Cornwall.
The three children use the surname Wales
George, Charlotte, and Louis used the titles of their parents, the then-Duke and Duchess of Cambridge, as their surnames, just as Prince Charles uses his title as his name. They were known to everyone at school as George Cambridge, Charlotte Cambridge, and Louis Cambridge because all three of the siblings shared the surname Cambridge.

However, they didn’t use that surname for long, though, as when King Charles succeeded to the throne, he transferred the title of Prince of Wales to Prince William, who in turn gave the three children the surname Wales.
The young royals refer to their grandfather as “Grampa Wales”
William and Harry used the surname “Wales” throughout their childhood, including in school, at university, and while serving in the military. Harry held the title of Captain Wales, while William was known as Lieutenant Wales.

In addition, the children refer to their father William as “Pops” rather than “dad,” according to a People magazine report. How cute!
