The Duchess of Cambridge, aka Kate Middleton, was supposed to have given birth to her second child by now, and the world is speculating on when Prince George's little sister or brother will arrive in the Lindo Wing of St. Mary's Hospital in London.
And as those dates have come and gone, here's what we know so far about Royal Baby Watch 2015, or #GreatKateWait, as the latest hashtag is calling the occasion.
* The Duke of Cambridge, aka Prince William, will be present for the birth of the baby, who will be fourth in line to the throne, behind his or her brother, father and grandfather, according to the Telegraph.
* The duchess's impending birth is creeping up on the country's general elections, which are slated for May 7.
* Another big question is if the duchess will be induced. Depending on doctor's orders, Middleton could be induced a week after her due date (which has been speculated as being April 23 or April 25) or as long as two weeks, putting Royal Baby No. 2's arrival at next week or later, according to the site.
* Parking restrictions around the hospital have been updated, according to the Telegraph, and will be extended further until May 5. The royals even sent breakfast treats to people waiting outside the Lindo Wing who were waiting for a glimpse of the #RoyalBaby action.
* Apparently, Prince Charles is rooting for a girl. While at a celebration, he told a celebrated Welsh Guard that "[W]e're hoping for a granddaughter!" the guard's daughter, Lynda Bateman, told the Telegraph.
* Prince Harry will likely miss the birth of his niece or nephew, as he's "down under" in Australia and New Zealand until May 16.
* As for the preferred names of the royal baby, Alice for a girl and Arthur for a boy are the popular frontrunners among informal voters, the site reports.
Until Royal Baby No. 2 makes his or her debut, we'll of course only be speculating. So check @KensingtonRoyal for the latest, official updates from Kensington Palace.
