We previously reported that Prince Harry and Meghan Markle have decided not to spend Christmas with the royal family in the United Kingdom, instead choosing to spend the holiday at their home in California. Despite this, a source close to the couple are saying that they are “incredibly excited” for Christmas this year, as they feel their 17 month-old son Archie can be actively “involved” in it for the first time.

“Christmas is Meghan’s favorite holiday and she cannot wait to get into the festive spirit. She and Harry will buy a ginormous Christmas tree for the new house and will decorate it as a family,” the source told Closer Weekly. “They’re excited about getting Archie involved this year and will let him pick out a couple of ornaments to put on the tree.”

The insider added that though Archie is still quite young, “he’s at an age where he can understand some of the concepts” behind the traditions his parents are teaching him.

“Meghan’s already bought him a Christmas children’s book,” the source said, adding that Harry and Meghan will also “leave a glass of wine for Santa Claus” on Christmas Eve.

While the royal family has long had a tradition of exchanging presents on December 24, Harry and Meghan are going a different route.

“The Sussexes will open their presents on Christmas Day morning as a family,” the source explained.

Harry and Meghan’s Montecito, California mansion will also be decorated with “stockings by the fireplace” in their living room.

Though Harry and Meghan are excited about Christmas, another source said that Queen Elizabeth is saddened that they have decided not to come home for the holiday.

“The queen’s Christmas will be very different this year because of [social distancing rules], [but] she’s urging Harry to return to the U.K. for the holidays,” this insider said. “She would love to see her grandson – and Archie, of course. It’s been so long.”

The source said that Meghan is “twisting” Harry’s arm to stay in the United States, but added that the couple is working on a compromise.

“They’re planning to spend [Christmas] at their new home and will fly back to the [U.K.] a day or so later in time for New Year,” the source said. “They’ll have to isolate for at least 10 days, but at least Harry will be reunited with his friends and family again.”
