Baby Archie Mountbatten-Windsor is just over two months old, but already there is chatter about when the newest member of the royal family might be getting a sibling.
"People are already speculating about baby number two for the Sussexes," the respected royal expert and the Vanity Fair royal reporter Katie Nicholl told Entertainment Tonight.
Now that Archie's christening has been and gone, and we've seen just how adorably besotted Harry and Meghan are with their little bub, it's not surprising that royal fans are wondering when the seventh in line to the throne will get a sibling.
"They absolutely want siblings for Archie, so possibly we will have a pregnancy announcement - a second pregnancy announcement for Meghan and Harry sometime next year - but, for the moment, the focus is obviously on Archie," Nicholl revealed.
Harry and Meghan have clearly taken to parenthood like ducks to water and have told their loved ones they would absolutely want to expand their brood.
"Sources close to the couple told me that they really would love to have a big family," royal expert Nicholl said.
"They are, by all accounts, amazing parents. They are loving parenthood."
While the couple have their own staff and significant financial resources at the ready to help, becoming parents has still been a new challenge for the couple.
"Their life has changed enormously and that was one of the things the sources I spoke to .... told me that this really has been a life-transforming event," Nicholl said.
"Yes, they're royals, yes, they probably have more help than the rest of us, but this really has turned their world upside down for the better. So, I think at the moment, they're focusing on Archie, but I know it's their plan to have more than one child."
The couple's decision to raise Archie out of the spotlight and have a private christening is an attempt to ensure that the royal baby has as normal an upbringing as is possible.
"You have to remember that Prince Harry grew up very much in the spotlight, never far away from the gaze of the cameras and at points in his life, that's been something he has resented," Nicholl said.
And that explains why Harry and Meghan have chosen to live at Frogmore Cottage in Windsor, away from the hustle and bustle of London, and Kensington Palace and Buckingham Palace.

"At Frogmore, they have essentially built a fortress, one of their closest friends told me it was their oasis, their sanctuary where they're going to raise their child away from the spotlight," Nicholl said.
"They are tucked away there, they are set in acres of beautiful green space, you cannot get close to the property and behind the walls of Frogmore cottage. Archie is enjoying, albeit a privileged lifestyle, a remarkably ordinary lifestyle."
