Princess Beatrice and Edoardo Mapelli Mozzi welcomed their first child on 18 September, and the couple are yet to announce their daughter's name.
In comparison, the Duke and Duchess of Cambridge, and the Duke and Duchess of Sussex typically took around two days to confirm their children's names.
However, there is one key difference for Beatrice, in that she is not a working member of the royal family. The new mum, 33, has a role as Vice President of Partnerships and Strategy at tech company Afiniti.

Beatrice's younger sister, Princess Eugenie, announced the name of her and Jack Brooksbank's son August 11 days after his birth on 9 February at the Portland Hospital in London.
Eugenie and Jack formally introduced their baby boy to the world on Instagram. Alongside a photo of the new parents smiling as they held their baby son's tiny fingers, Eugenie wrote: "We wanted to introduce you to August Philip Hawke Brooksbank. Thank you for so many wonderful messages. Our hearts are full of love for this little human, words can't express. We are excited to be able to share these photos with you."

Similarly, Beatrice and Eugenie's cousin Zara Tindall and her husband Mike also kept royal watchers waiting, choosing to announce their second child Lena's name nine days after the birth.
A spokeswoman for the couple at the time said: "Zara and Mike Tindall have named their baby daughter Lena Elizabeth. It is just a name they liked."
Mike even took to Twitter to confirm how his daughter's name was announced, writing: "Pronounced like Lay-na."
Back in 1988, the Duke and Duchess of York took two weeks to confirm Princess Beatrice's name. The Queen also didn't share Prince Charles' moniker publicly for a month after his birth in 1948.
