Archie Harrison Mountbatten-Windsor, the son of Prince Harry and Meghan Markle, has been christened by the Archbishop of Canterbury in a private ceremony.
The royal baby was baptized in front of close family and friends in the private chapel at Windsor Castle on July 6.
Prince William and Kate Middleton attended but were not thought to have their children with them.
Queen Elizabeth II did not attend due to a prior engagement.
Prince Charles and the Duchess of Cornwall were reported to have arrived at the ceremony by helicopter and Meghan Markle’s mother, Doria Ragland, also attended.
A full list of the 25 guests has not been made public, but Lady Jane Fellowes and Lady Sarah McCorquodale – the sisters of Prince Harry’s mother, the late Diana, Princess of Wales – were pictured in an official photograph taken at the christening.
A Royal Communications spokesperson said: “The Duke and Duchess of Sussex are overjoyed to share the happiness of this day, and would like to thank everyone around the world for their ongoing support.
“They feel so fortunate to have enjoyed this special moment with family and Archie’s godparents.”
The Duke and Duchess of Sussex opted to exclude the press and the public from the day and chose not to reveal the names of Archie’s godparents.
Instead of having press photographers, fashion photographer Chris Allerton – who took their wedding photos – captured the special moment, with two pictures released to the public and posted on the couple’s Instagram account.
Chris Allerton said he was “honored” to take the official photographs and “be part of such a joyous occasion”.
However, Prince Harry and Meghan did follow some royal traditions.
Archie wore a handmade replica of the royal christening robe which was made for Queen Victoria’s eldest daughter.
The robe, which has been worn by royal infants on the occasion of their christening for the last 11 years, was made by Angela Kelly, dressmaker to the Queen.
The ornate Lily Font, commissioned by Queen Victoria and Prince Albert for the baptism of their first child Victoria, Princess Royal, in 1841, was also used – as was water from the River Jordan.
As the first born son of a duke, Archie could have become Earl of Dumbarton – one of Prince Harry’s subsidiary titles – or have been Lord Archie Mountbatten-Windsor, but instead he will simply be Master Archie Mountbatten-Windsor.
On which parent the baby resembled more, Prince Harry said: “Everyone says that babies change so much over two weeks.
“We’re basically monitoring how the changing process happens over this next month really. But his looks are changing every single day, so who knows.”
Pictures of the new family’s first photocall were then shared on the SussexRoyal Instagram account.
The post said: “The Duke and Duchess of Sussex are delighted to share their first public moment as a family.”
The images shared on social media were taken by Chris Allerton, who was the couple’s private wedding party photographer, and took the picture of the newlyweds watching fireworks in the grounds of Frogmore House at their evening reception.
The royal baby, who is seventh in line to the throne, was delivered at 05:26 BST on May 6, with Prince Harry saying after the birth that he and Meghan were “absolutely thrilled”.
Prince William has welcomed his brother to “the sleep deprivation society that is parenting”.
The Duke of Cambridge – a father-of-three – said he looked forward to seeing the new parents “when things have quietened down”.
Prince Charles has also expressed his joy at the birth.
During an official visit to Germany with the Duchess of Cornwall, the Prince Wales said: “We couldn’t be more delighted at the news and we’re looking forward to meeting the baby when we return.”
