Louis, who was born on Monday, April 23 at St. Mary's Hospital's Lindo Wing, was christened on Monday, July 9, surrounded by close relatives and immediate family. Not present at the service were his great grandparents, Queen Elizabeth and Prince Philip, though their absence had reportedly "been mutually agreed by the Queen and the Cambridges some time ago" and was "not made on health grounds."

Prior to his baptism, Kensington Palace revealed the names of Louis' six godparents, all close friends and extended family of his parents. His godparent were announced to be Lady Laura Meade; Hannah Carter, a close friend of Kate's from Marlborough College; Lucy Middleton, Kate's cousin; and close friends Nicholas van Cutsem, Harry Aubrey-Fletcher and Guy Pelly.

Following the christening, the British Royal Family released a series of photos from the big day. The images, captured by Matt Holoak of Camera Press, who also photographed Prince George for his third birthday, were taken in and outside of Clarence House and included several members of the Royal Family.

In one photo, the little prince's parents and siblings are shown sitting on a couch as other members of the Royal Family, including Prince Harry, Meghan Markle, Camilla Parker Bowles, Prince Charles, Carole and Michael Middleton, Pippa Middleton, James Matthews and James Middleton, stand behind them.

Middleton, wore an Alexander McQueen dress for the event and a Jane Taylor headpiece, has slowly been stepping back into her royal duties following the April birth of Prince Louis, her and Williams' youngest son. Although she was absent from the Garden Party in May, she attended the Trooping the Colour and later the Royal Air Force centenary.

Most recently, the royal mom-of-three made her first solo outing with the newly minted Duchess of Sussex, Meghan Markle. The two attended the Wimbledon women's single finale on Saturday, where they met former women's tennis champions, ball boys and girls before the matches, and cheered on Markle's close friend Serena Williams during her match against Angelique Kerber.
