From Camilla's first marriage to Andrew Parker Bowles, King Charles has five royal grandchildren and five step-grandchildren.

King Charles helped his step-granddaughter Eliza on Buckingham Palace's balcony following Prince William & Kate Middleton's wedding.

After Prince George was born, Charles began collecting gifts for his new grandson.

At the Sandringham Flower Show in 2013, he appeared delighted to receive a teddy bear for George.

Charles listened intently to George's toddler ideas as he developed.

They spoke following a charity polo match in 2015, during which Charles appeared to praise George's shoes.

In 2018, Charles, his oldest son, and grandson, along with the rest of the royal family, baked a Christmas pudding for military veterans.

Charles held Prince Louis close when he was a little boy.

In June, Prince Louis sat on his grandfather's lap during The Mall's Platinum Pageant to commemorate Queen Elizabeth's platinum jubilee.

At this year's Trooping the Color, 4-year-old Louis seemed to get scared when military planes flew over Buckingham Palace.
