It’s official: Prince William and Kate Middleton are expecting baby number three.

Over the weekend, Kensington Palace sent out an official announcement that read: “Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child.”

The announcement added that the Queen is delighted with the news.

And while the palace isn’t releasing too many details on the baby just yet, there are a few key facts we already know. Keep reading to learn more about the child that will push Prince Harry even further from the throne.

Kate is once again suffering from morning sickness.

In the statement, Kensington Palace noted that the Duchess is once again suffering from hyperemesis gravidarum, a severe form of morning sickness. She suffered from the same condition through her pregnancies with Prince George and Princess Charlotte.

The newest baby will be fifth in line for the throne.

The line of royal succession changed just before the birth of Prince George. In 2013, the rule changed so that princes no longer take precedence over their sisters, bringing an end to the system of male preference, which had been in place since the Act of Settlement of 1701. So, if George were to abdicate, Charlotte would take the throne, regardless of whether or not the newest bundle of joy is a boy or a girl. Sadly for Harry, he’s been pushed to sixth in line.

It will be a spring baby.

The Duke and Duchess have yet to reveal a due date, but if Middleton were 12 weeks pregnant, that would put her due date somewhere within March of 2018. However, as Town&Country explained, Middleton was forced to reveal her pregnancies prior to the crucial 12-week mark due to her extreme morning sickness with both previous children. If she’s less than 12 weeks pregnant, the newest royal will arrive sometime in April or even early May.

The baby will have more than one name.

While no official names have been announced yet, bookies across the world are already setting their sights on a few traditional monikers including Alice, Elizabeth, and Victoria for a girl and James, Arthur, or Philip for a boy. The Sun additionally reported that there are a few outliers in the betting world who believe if the third child is a girl the Duke and Duchess will name her after William’s late mother, Princess Diana.

And while members of the royal family do not need a surname, they will likely keep with tradition by giving the child several names, like Prince George, whose full name is George Alexander Louis, or Charlotte, whose full name is Charlotte Elizabeth Diana.

The baby will likely be born in the Lindo Wing of St Mary’s Hospital in West London.

Like his or her siblings, the newest royal baby will likely be born in the famed St Mary’s Hospital.

The highly private Lindo Wing was also where both Prince William and Prince Harry were born. Reporters are expected to arrive several days before the birth and will simply have to wait for the Duke and Duchess to exit the hospital with their latest bundle of joy and hope for a simple wave to the cameras before they buckle up their little one and make the drive home as a family of five.
