The countdown to the birth of the royal baby is well and truly underway.
And while Meghan’s exact due date remains a mystery, speculation is rife that the Duchess of Sussex will give birth mid April.
So just how will we know for sure when and where the mum-to-be will welcome a new little princess or prince into the world?
Well, as royal baby fever gathers momentum, here are a few clues to get fans excited.
Firstly, and despite reports she's already on maternity leave, if Meghan follows in sister-in-law Kate’s footsteps, she will wrap up her royal duties about a month before her due date. This will be confirmed by Kensington Palace in an official statement.
“Today’s public engagements by The Duke and Duchess of Cambridge will be Her Royal Highness’ last before starting her maternity leave,” a statement read prior to Kate giving birth to Prince Louis last year at the Lindo Wing.
The world can expect the same for The Duke and Duchess of Sussex when the time is right. And royal insiders say that could be any day now.
But the biggest clue of them all comes down to...parking restrictions.
While it’s not yet known which hospital Meghan and Prince Harry have selected to welcome their first born, parking restrictions, notices and barriers are set to be put into place over the coming weeks in preparation for the world's media to descend in London very soon.
According to UK reports, this usually occurs about two weeks before the birth of a royal baby.
For example, when Kate gave birth to Prince Louis, parking was suspended for a three week period before she had even checked in to the Lindo Wing.
What also remains top secret is just how long Meghan will remain on maternity leave.
But one thing we know for sure is that Prince Harry will be by her side every step of the way and is even planning on taking a few weeks off himself to spend with baby Sussex once he or she arrives.
