Prince William and Kate Middleton’s youngest child, Prince Louis, is only 6 years old, but he’s already developing a goofy personality. Remember when he stole the show at King Charles’s coronation? Or when he looked hilariously amused at Trooping the Colour?

Prince George, Princess Charlotte, and Prince Louis attended church in Sandringham on Christmas Day alongside their parents, Kate Middleton and Prince William. After the service, the Prince and Princess of Wales' children met with royal fans outside who showered them with a plethora of sweet gifts in honor of the holiday.

"Cancer just really does resonate with so many families," the Princess of Wales told royal fans at Sandringham.

The Princess of Wales revealed her cancer diagnosis in March and confirmed in September that she had completed her chemotherapy treatments.

A visibly moved Kate, who fought an undisclosed form of cancer this year, expressed her gratitude to healthcare professionals for all their “hard work.”
