US President Donald Trump’s youngest child Barron has turned 13.

Barron, who attends a private school in Maryland, and his mother Melania are keeping to tradition and spending the spring break holiday at their home in Palm Beach, Florida.

The Republican president was in Washington, with plans for a trip to Ohio later.

There was no word on plans for a birthday celebration for Barron, whose full name is Barron William Trump.

But the first lady tweeted a photo of a gold-tone Mylar balloon in the shape of 13 and a caption that said “Happy Birthday BWT” followed by three hearts.

President Barack Obama’s daughters Malia and Sasha also turned 13 in the White House.
