Here's everything you need to know about the latest addition to the royal family…
When will the royal baby's name be announced?
Royal parents usually take around two days to announce a new baby's name, with the Duke and Duchess of Sussex revealing their son Archie's name on 8 May 2019 after his birth on 6 May.
However, Prince Andrew and Sarah waited two weeks before unveiling their first child Princess Beatrice's name in August 1988, while the Queen didn't share Prince Charles' name publicly for a month after his birth in 1948.
Arthur is the bookies' favourite for the new royal baby's name with odds of 5-1, followed by James at 6-1 and then Frederick, Edward and Albert all at 8-1, while it is 10-1 for Alexander, Hugo or Alfred.

Where is the royal baby in the line of succession?
The tot is 11th-in-line to the throne after his mother Eugenie. This has also meant that the baby's great-uncle, the Earl of Wessex, has now moved down one place to 12th.
Eugenie's son will move further down the line with the arrival of new additions to the family, including when the Duke and Duchess of Cambridge's children, Prince George, Princess Charlotte and Prince Louis, grow up and have children of their own.

Will the royal baby have a title?
While Eugenie is Her Royal Highness Princess Eugenie of York, it doesn't automatically mean that her son will also inherit a title.
As things currently stand, the royal baby will not have a title because these are passed down the male line and Jack does not have a title.
However, the Queen could decide to intervene and give Eugenie's husband an earldom or issue a Letters Patent amending the rules.
When will the royal baby be christened?
Royal babies are usually christened when they are around three or four months old, although Princess Eugenie's christening did not take place until she was nine months old.

Eugenie was baptised at St Mary Magdalene Church in Sandringham in December 1990 and she was the first and only royal baby to date, to have a public christening.
New parents Eugenie and Jack could decide to break with tradition and follow suit with a public baptism for their first child.
