The Swedish royal family has a name for its new little addition. On Wednesday, King Carl XVI Gustaf announced that Princess Madeleine’s baby boy will be called H.R.H. Prince Nicolas Paul Gustaf, Duke of Angermanland, a province in northern Sweden. Princess Madeleine, 33, gave birth to the healthy baby boy Monday. 

Madeleine gave birth to her second child just two days after she attended her brother Prince Carl Philip’s wedding to Sofia Hellqvist on Saturday.

The baby weighed 6 pounds, 7 ounces; measured 19 inches and, according to press officer Margareta Thorgren, has his father Chris O’ Neill’s chin. Royal watchers were surprised by the spelling of Nicolas, with Niklas being the more common Swedish spelling. The little royal’s middle name Paul honors Chris’ father Paul Cesario O’Neill, who died in 2004, while Gustaf is a traditional name taken by the male members of the royal family, according to Hello.

In the first official photo op, Prince Nicolas is pictured in gray cotton pants and a matching sweater with a little white collar. As Chris, 40, left Danderyds Sjukhus Hospital outside Stockholm on Monday with his daughter, Princess Leonore, he told the waiting crowd: “It went very well. I think [Leonore] mistook him for a doll.”

The first picture of Nicolas was shared by the royal family’s Facebook page showing the baby boy peacefully sleeping on Tuesday. Madeleine, 33, spent the first night bonding with her newborn son in hospital, but the pair, who welcomed their first child, daughter Princess Leonore, in 2014, are now at home and returning to life as a foursome. Little Nicolas will now be sixth in line to the throne after his aunt Crown Princess Victoria, cousin Princess Estelle, his uncle Prince Carl Philip, his mother, and Leonore.

To mark the royal baby’s arrival, soldiers on the Stockholm island of Skeppsholmen and other military locations around the country fired a series of 21-gun salutes. Among the first visitors pictured arriving at the hospital were Madeleine’s parents, King Carl Gustaf and Queen Silvia. The royal couple were all smiles and waved to the crowd when they went to meet the newborn prince, who is their first grandson and third grandchild.
