This Timeline Of Kate Middleton's Third Pregnancy Will Get You So Excited For The Big Arrival

All pregnant women have a big responsibility to keep their unborn babies safe and healthy. However, Kate Middleton's responsibility might just be slightly greater than that of your average mom-to-be. As the wife of Prince William, who is second in line to the British throne, Middleton's first baby was deemed third in line to the throne before he was even born. Imagine how it must feel to know you are literally carrying the future King in your uterus! Since giving birth to Prince George, Middleton has also given birth to Princess Charlotte, and she is currently pregnant with her and Prince William's third royal baby. With her due date fast approaching, it seems like the perfect time to reminiscence over Kate Middleton's pregnancy timeline with royal baby number three.

While it's pretty much a guarantee that Prince George will become king after his father either passes away or abdicates the throne, the chance of Princess Charlotte or their third child becoming monarch is much lower, as any future children Prince George has will cut the line of succession in front of Prince George's siblings. However, you never know!

Here's a look back at the biggest moments in Middleton's pregnancy with her imminent third child, whose arrival is sure to throw a wrench in the royal family's routine (in a good way, of course).

September 2017: It's Announced That Middleton Is Already Suffering From Hyperemesis Gravidarum

Just one minute after tweeting that Middleton was expecting, Kensington Palace posted a press release explaining that the Duchess was suffering from Hyperemesis Gravidarum. HG is severe morning sickness, and some women who suffer from HG vomit up to 50 times per day, as per the U.K.'s National Health Service. The disease also affected Middleton during her first two pregnancies — even sending her to the hospital — so Middleton is seriously a champ for enduring multiple pregnancies.

In September, the Daily Mail reported that Middleton was considering a home birth in order to avoid the public spectacle of a hospital birth. However, a report from Us Weekly released in March suggests that Middleton has a very detailed birth plan in place for a hospital birth. Looks like fans will have to wait and see if she emerges on the hospital steps with baby number three like she did following Prince George and Princess Charlotte's births!

And that pretty much brings us to the end of March, just days before the start of April, the month Middleton is due. She hasn't revealed whether or not she's due at the beginning or the end of April, but you can safely count on royal fans to stay on their toes all month long.
