They are just a few days old, but the newest members of the Danish royal family are already receiving visitors.
Since their arrival on Saturday, Crown Prince Frederik and Crown Princess Mary's twins have been inundated with friends and family eager to see both the newborns, and of course, their mum.
Among the first to visit was Countess Alexandra, her husband Martin Jorgensen and her children with ex-husband Prince Joachim, Prince Nikolai, 11, and eight-year-old Felix.

The family were seen arriving at Rigshospitalet, with the boys looking particularly excited about the chance to meet their brand new cousins.
Speaking later to the press about their visit, Alexandra said Mary was doing well, joking that Frederik seemed to be more tired than his Australia-born wife.
She added that, like her son Nikolai, she thought the new little princess looks very much like her big sister, Isabella, three, who, along with five-year-old Prince Christian, has already seen her new siblings.
Soon after the birth of the as-of-yet unnamed twins, their dad Frederik returned to Amalienborg Palace to pick his excited eldest children up and take them to the hospital, arriving with them through a different entrance to avoid the press.
Other visitors at the hospital have included Mary's father John Donaldson, her private secretary, lady-in-waiting, and her stylist and friend Anja Camilla Alajdi who has revealed that the Crown Princess is already up and about.
"She is doing well, she is doing really well and looks good," said Anja, saying of the little ones: "They are very dear, very sweet and still very small.
"But I think they are adorable. They have lots of hair on their heads and have great colouring."
Due to a pre-scheduled trip abroad, Frederik's younger brother Prince Joachim and his wife Princess Marie – who became a first-time mum to Prince Henrik in May 2009 – have so far been unable to meet the twins, but have been on the phone to offer their congratulations.
In keeping with tradition, the names of the newborn babies will not be announced until their christening, which takes place three months after their birth.
It is not yet known when Mary and the twins will leave hospital.
