King Charles III was captured on camera aged seven, and even a bump on the head didn't stop the young royal smiling.

The slight mishap didn't stop Charles smiling though and he turned around to his mother, Queen Elizabeth II, and father with a grin on his face.
Despite not looking too fazed, he did rub the back of his head as he hopped off the swing after the fun was over.

This rare candid footage was taken during a family trip to Balmoral in September 1955 and gives an insight into the wholesome home life of the royal family when they are away from the world's press.
Royals are a fan of traditional looking swings
Charles' younger sister Princess Anne was also present on the holiday, and she was seen standing next to the swing, looking on as her brother was pushed higher and higher.
The swing itself looked to be constructed with two tree trunks, and traditional wooden swings are still a commonplace feature in many royal homes.
Prince George has been spotted on a beautiful wooden swing too
We've seen that Prince Andrew and Sarah Ferguson's daughter Princess Eugenie has a personalised swing from her childhood in the garden of Royal Lodge.
Fans have also seen Prince George standing on a similar swing at his family home, personalised with his mother and father's names. The swing that he proudly stood on was engraved with 'William and Catherine' and was in fact a wedding gift to the royal couple in 2011. It was created by The Oak & Rope Company, a family business based in Kent.
