Kate Middleton, 36, has been given the due date for her third child, according to sources.
The Duchess of Cambridge is already a mother-of-two to Prince George, four, and Princess Charlotte, two.
But that is set to change imminently, an the baby may well be born on a very special day.
Sources have said the third royal baby could arrive on 23 April, St George’s Day.
A source told the Sun: “There’s no certainty with due dates of course but the Duchess is working off a date around St George’s Day and it would be a lovely patriotic coincidence if he or she were born then.”
St George’s Day is a celebration of English Christian figurehead Saint George.
The religious figure is said to have slain a dragon in the UK, although accounts of this event are unverifiable.
Now the day is often a day of general celebration, and a good excuse for many Britons to go to the pub or have a meal with family.
However, Kate’s third baby could be born on another special day, if the birth comes later than expected.
The royal source added: “Or if she’s very late, as she was with George’s birth, she could even make it a very special wedding anniversary present to William, as they celebrate seven years of marriage on the 29th April.”
When will Kate Middleton go on maternity leave?
The Duchess of Cambridge has been working hard in 2018, taking on two new patronages, as well as numerous public appearances.
When will Kate Middleton’s last public appearance before she gives birth be?
It’s been announced that on Monday 12 March she will attend the Commonwealth Service at Westminster Abbey on Commonwealth Day alongside other members of the royal family.
Maternity leave in the UK is up to 52 weeks, and the easiest that it can be taken 11 weeks before the expected week of childbirth.
When Kate gave birth to her first child Prince George on 22 July 2013 she began her leave on June 13, 39 days before she gave birth – just over five weeks.
