Why the next royal baby might not be a Prince or Princess

The Duke and Duchess of Sussex have announced that they'll be welcoming their first child in spring 2019.

But the latest addition to the royal family might not be a Prince or Princess.

Royal etiquette expert William Hanson told Mashable that the royal baby's title all depends on the Queen's decision.

"Any title given to the child will be at The Queen’s discretion and whim," Hanson explained. "Due to Prince Harry’s status as 6th in line to the throne, and as the child’s as 7th once born, it is unlikely it will be made a Prince or Princess, but we won’t know until after the birth."

"It is likely that it will be The Lord or The Lady Windsor. If the child is male it may take Prince Harry’s courtesy title - Earl of Dumbarton,” Hanson tells Mashable.

According to the Evening Standard, Prince Harry's great-great-grandfather, King George V, limited titles within the royal family a century ago, meaning that children born too far down the lineage are not granted an HRH (Her/His Royal Highness) title.

For the child to become a Prince or Princess, the Queen will have to issue a Letters Patent, a written order granting a person a title.

The Queen did exactly that at the birth of Prince George, son of Prince William and Kate Middleton, to ensure that all their children would have titles, and not just first born George.

Title or no title, to say the world is excited for Harry and Meghan's first child would be an understatement.
