Prince George, Princess Charlotte, and Prince Louis, the three children of the Prince and Princess of Wales, have the cutest nickname for Prince Charles and his wife, Queen Consort Camilla.
In honor of his former title as Prince of Wales, the young royals refer to their grandfather as “Grampa Wales,” while the Queen Consort has previously revealed that they refer to her as “GaGa.”

She discussed her adorable moniker with the Daily Mail in 2016: I’m not sure if it’s because they believe I’m [gaga], She spoke. It’s funny, but it’s also really sweet.
We also got a glimpse of Charles’ tender side as a grandfather during the Queen’s Platinum Jubilee pageant in June, when he entertained Prince Louis on his lap during one of his first significant public appearances.
In addition to being the step-grandmother of King Charles’ grandchildren, Camilla, the new King’s wife, also has grandchildren of her own.

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