The news comes as the Duke and Duchess of Sussex break away from the royal tradition of spending Christmas at Sandringham with the Queen.
"The Duke and Duchess of Sussex are looking forward to extended family time towards the end of this month. Having spent the last two Christmases at Sandringham, [the couple] will spend the holiday this year, as a new family, with the Duchess’ mother Doria," Buckingham Palace wrote in a statement to royal correspondent Omid Scobie.
The royal couple are believed to be taking a six-week break following Prince Harry's appearance at Royal Albert Hall on Sunday.
Royal experts have debated the reason for their snub, which hasn't helped rumours of an ongoing rift between Meghan and Harry and the Royal Family.
"They need some time away to recharge and decide their plans for next year," a source told The Sun. Others have suggested it may be due to concern for Archie.
"Christmas at Sandringham can be quite stressful so perhaps they don’t want to go with Archie at such a young age," hypothesised royal biographer Ingrid Seward.
However, she also noted Sandringham has always played host to "many many children" over the years and is "well set up for them."
"It does seem to be nothing to do with Archie and to do with their own personal feelings," she concluded. What's more, Ms Seward argued that their decision is a sad one considering the Queen and the Duke of Edinburgh are "in their dotage."
"The Queen might be a little hurt but she’s far too gracious to ever let it show or be known," the royal expert added.
Buckingham Palace is yet to comment further on the Royal Family's movements over Christmas.
