Princess Madeleine of Sweden shared a rare photo of her only son, Prince Nicolas, to mark his sixth birthday on Tuesday.
The sweet Instagram snap showed the young royal leaning his head on a steering wheel of what appears to be a golf cart, while a beach could be seen behind him.
The royal mum's caption read: "Happy Birthday, dear Nicolas! We love you to the moon and back. Keep on truckin'!"

Prince Nicolas, Duke of Ångermanland was born in Stockholm on 15 June 2015. He arrived just days after his uncle Prince Carl Philip tied the knot with Sofia Hellqvist.

In the run-up to the wedding, there were reports that Princess Madeleine could miss her brother's nuptials due to the advanced stage of her pregnancy, but she and Chris attended the happy occasion with their eldest daughter, Princess Leonore.
In an interview with Swedish magazine, Mama, in 2019, Madeleine revealed that she was actually having contractions during the wedding, and her son, Prince Nicolas, was born two days later.

Princess Madeleine is the youngest child of King Carl XVI Gustaf and Queen Silvia.
In 2019, the king made some changes to the royal house, announcing that the children of Prince Carl Philip and his wife Princess Sofia, and the children of Princess Madeleine and Christopher will no longer be members of the royal house.
This meant that Carl Philip's sons, Prince Alexander, Prince Gabriel, and Prince Julian, as well as Princess Madeleine's children, Princess Leonore, Prince Nicolas and Princess Adrienne, lost their style of Royal Highness and in future will not be expected to perform duties incumbent on the head of state.
