The King celebrates his 75th birthday today and what a year it has been for the monarch!
Charles was officially crowned at his and Queen Camilla's historic coronation at Westminster Abbey on 6 May, with the King marking the first year of his reign in September.
There has also been state visits, his first birthday parade and his first summer as host at Balmoral.
But we're taking things back to the King's childhood, where he had a loyal playmate in the form of his younger sister, Princess Anne, and was doted on particularly by the late Queen Mother.
Discover some of King Charles’s cutest moments from his royally-lavish lifestyle as a child…
