Melania, 47, announced the move with a Twitter photo showing the Washington Monument from a White House window. She wrote: “Looking forward to the memories we’ll make in our new home! #Movingday.”
Trump, 70, Melania and Barron were shown arriving at the famous home aboard Marine One on Sunday. Trump’s youngest son wore a shirt that read “The Expert” and carried a fidget spinner.
White House officials confirmed the move to PEOPLE in April, noting that Melania and Barron would move from their home at Trump Tower in New York City once Barron finished the academic year.
However, multiple sources previously said that Melania was hesitant to live in the White House.
“Melania wants to stay in New York while her son goes to school,” a Palm Beach source said.
“I don’t know if she will ever live away from New York full-time, especially with her son in school there. She loves her home in Manhattan and her independent life.”
Barron will be the first male child to live at the White House since John F. Kennedy Jr. in 1963.

The move could appease critics who have demanded that Melania move to the White House — or pay for the security costs at Trump Tower herself.
The New York Police Department has said that protecting Melania and Barron as they lived in New York would cost between $127,000 and $146,000 per day.
