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

Following Prince William and Kate Middleton's wedding, King Charles assisted his step-granddaughter Eliza on Buckingham Palace's balcony.

Following the birth of Prince George, Charles began collecting gifts for his new grandson.

He appeared pleased to receive a teddy bear for George at the Sandringham Flower Show in 2013.

As George developed, Charles listened intently to his toddler ideas.

They met after a charity polo match in 2015, during which Charles appeared to compliment George's shoes.

Charles, his eldest son and grandson, and the rest of the royal family baked a Christmas pudding for military veterans in 2018.

When Prince Louis was a child, Charles held him close.

When military planes flew over Buckingham Palace during this year's Trooping the Color, 4-year-old Louis appeared to be scared.
