The long wait for the Royal Princess may be over, but the wait to discover her name will go on a little longer, after the Duke and Duchess of Cambridge kept mum over what they will call their daughter.
At a family get-together in Kensington Palace, the Duke and Duchess were joined by the Prince of Wales, the Duchess of Cornwall, Kate's mum Carole, father Michael and sister Pippa Middleton, where the issue of the Princess's name was surely the question on all of their lips.
Whether their curiosity was satisfied, no one was telling, as Kensington Palace released a mid-afternoon statement saying no name would be made public until today at the earliest.
Alice and Charlotte remain the bookmakers' favourites, with Victoria, Olivia and Elizabeth also heavily backed by the public.
Prince Harry, who is in Australia on attachment to the country's defence force, said of his new niece: "She is absolutely beautiful. I can't wait to meet her."
A Kensington Palace spokesman said: "The Duke and Duchess are hugely grateful for the messages of congratulations they have received from people all over the world.
"It means a great deal to them that so many people have celebrated the arrival of their new daughter."
The Duke and Duchess, who left hospital with their daughter on Saturday evening, spent the day at Kensington Palace, where Carole and Pippa Middleton were their first visitors. Just as they had done with Prince George, the Middleton family beat the Royal family to the crib.
When Prince George was born two years ago, Carole and Michael Middleton arrived in a taxi at the Lindo Wing long before the Prince of Wales.
This time, Carole Middleton, with her daughter Pippa in the passenger seat, drove through the gates of Kensington Palace shortly after 11.30am, and spent more than an hour with her daughter and granddaughter before the Prince of Wales and Duchess of Cornwall arrived, smiling and waving, at 12.50pm.
Michael Middleton arrived alone shortly afterwards, wearing a stern expression.
The two families spent an hour-and-a-half together before the Duke and the Duchess left at 2.20pm, looking delighted with the latest addition to the family.
The only other visitor was Emilia Jardine-Paterson, the Duchess's close friend who was one of her classmates at Marlborough College.
She is a godmother to Prince George.
Queen Elizabeth and the Duke of Edinburgh are expected to meet their fifth and latest great-grandchild when the Duke and Duchess take their children to Anmer Hall in Norfolk this week. It is just two miles from Sandringham, where the Queen spent the weekend.
Seasoned royal-watchers believe Diana, a 10/1 shot, may well be one of the Princess's middle names, together with Elizabeth. Other names that have attracted significant numbers of bets include Alexandra, Mary, Grace and, Rose. (© Daily Telegraph, London)
