There is no evidence that Donald Trump’s youngest son, Barron Trump, is autistic. He seems to be a normal boy who appears healthy and well-adjusted to his surroundings. He was born in 2006 and he seems to be smart. He seems to make friends and gets along with others because of his enjoyment of both watching soccer and playing soccer with his friends on a soccer team in Washington D.C. Judging Barron is difficult since he is kept out of the spotlight probably by his mother especially during the campaign and during the election.
Barron stayed in New York City until the end of the 2017 school year which was probably around the beginning of June because he moved to the White House in June, 2017.
