The royal family welcomed the son of Meghan Markle and Prince Harry into the world with a website just for him.
There was just one problem: Someone accidentally introduced Archie Harrison Mountbatten-Windsor as the “first child of the Duke and Duchess of Cambridge.”
What they meant was of the Duke and Duchess of Sussex, social media was quick to point out.
“Someone must tell [Catherine] she just had a baby without her consent,” one Twitter user joked.
The mistake has since been corrected.
Prince William did say he can't wait to meet his new nephew, though.
"We’re absolutely thrilled and look forward to seeing them in the next few days.... I’m very pleased to welcome my brother to the sleep deprivation society that is parenting!" he told local reporters.
Archie was born on Monday morning, and Meghan and Harry showed him off Wednesday at St. George’s Hall in Windsor Castle.
The new bundle of joy is seventh in line for the throne.
