Prince Harry and Meghan Markle will have to follow royal protocol when it comes to naming their upcoming baby.

According to Katie Harris, a journalist for Express, the Duke and Duchess of Sussex would have to delay the announcement of the name of their baby. Royal commentator Victoria Arbiter explained why royals usually do this.

"On one hand there's a desire to inform the families before a public declaration is made and any new parent appreciates having a little private time to get to know their new addition before the onslaught of announcements," Arbiter explained.

"Royals, however, also have to consider the great responsibility in naming a new member of the family and I expect they want to be a hundred percent certain of their choice before announcing the name and sealing the baby’s place in history."

Prince William and Middleton abide by this rule. In fact, they waited for a couple of days before they announced the names of their three kids.

Middleton delivered Prince George on July 22 and only announced his name after two days. When the Duke and Duchess of Cambridge welcomed Princess Charlotte on May 2, they only announced her name on May 4.

However, the announcement for the couple's youngest child took longer. It took four days before Prince William and Middleton announced that the newest addition to their family is Prince Louis Arthur Charles.

It is believed that the delay was due to the Prince of Wales. Prince Charles was in France to commemorate Anzac Day when Prince Louis was delivered. So, the future king wasn't able to meet his youngest grandchild, but he immediately issues a warm welcome to the newest addition to the Cambridge family.

In related news, there is no truth to rumors claiming that Prince Harry and Markle are leaving the royal family due to their baby. OK! magazine reported that the Duke and Duchess of Sussex are reported to "turn their backs on the monarchy." The tabloid added that "Harry will be giving up his title and his $50 million trust fund."

Gossip Cop insisted that if Prince Harry does it he "would neither have money to support his wife and baby nor a home anymore in Kensington Palace in which to shelter them."
