Now that we know his full name, speculation around when we'll get another sighting of baby Prince Louis is already mounting.
With the royal wedding just a few weeks away, Prince Harry and Meghan Markle's big day appears to be the obvious event for the infant's next formal outing. Of course, the Duchess of Cambridge carrying her newborn son in her arms is one of the many moments that the crowds of fans will no doubt be waiting for.
But according to royal experts, an appearance from the newest member of the royal family is unlikely.
"I would be surprised if they took the baby to the wedding, simply because he might detract from the main event, and if he cried and had to be taken out, that would become the story," explains Penny Junor, journalist and author of Prince Harry: Brother, Soldier, Son. "But I am sure he will be at Windsor waiting in the wings somewhere because I imagine Kate is breast feeding and will need to feed him," she adds. "My guess is we won't see him until it's all over."
Marcia Moody, who was written biographies on both Kate and Harry, agrees. "I think it's unlikely that we will see the new baby at Harry and Meghan's wedding," she says. "Despite their big day being a lot more low-key than most royal nuptials, it's still an important royal event and a level of protocol will be required."
So, with Prince William taking on the best man duties, and Kate keeping an eye on Prince George and Princess Charlotte (who are still tipped to be a part of the wedding party), there's one member of the royal household who could be indispensable on the day - the royal nanny. And it's likely she'll be just moments away from the St George's Chapel ceremony, inside Windsor Castle.
"In Maria Borrallo the Cambridges have an experienced and trusted nanny, and Windsor Castle isn't far from Kensington Palace so it wouldn't take Kate long to get back to the baby," Moody adds.
Given that baby Louis was only born on 23 April and will be less than four weeks old on 19 May, his absence from the celebrations does make sense. While newborns can go out in public soon after birth, some experts say it's advisable to avoid taking them to crowded places while they are still so young.
"The general recommendations are to minimise public exposure in the first month of being born," says Tim Ubhi, a spokesperson for the Royal College of Paediatrics and Clinical Director of the Children's E-Hospital. "This is to protect against exposure to germs, but it's also important for families to find the right balance and expose their newborns to fresh air. Parents have to take a pragmatic approach - they have to live life!"
With the royal baby's first big moment in the spotlight taking place just hours after he was born at St Mary's Hospital, who knows - Prince Louis might be ready for a wedding after all.
