The child is doing well.

Former first son Barron Trump is doing “great” since enrolling at New York University this fall, Melania Trump told Fox News’ “The Five” on Tuesday.

“He loves his classes and his professors,” the former first lady said. “He is doing well, doing well and enjoying being back in New York City.”

The Post spied 18-year-old Barron, who towered over his Secret Service staff at 6 feet 4 inches as he walked through the Washington Square campus on September 4, wearing a smart white polo and stylish black Adidas Gazelle sneakers.

The 45th president confirmed to the Daily Mail the same day that his son attended NYU’s Stern School of Business, calling it “a very high-quality place” and noting that Barron “liked” it.

Donald and Melania’s only son is expected to commute from Trump Tower in Midtown to attend classes in Greenwich Village.

“He’s always been a very good student, he’s smart,” Trump previously told The Post of Barron, who graduated in May from the elite Oxbridge Academy in West Palm Beach, Florida.

It is unclear whether stricter security measures will be put in place for Barron at NYU after his father survived two assassination attempts earlier this year.

Barron made his political debut on July 9, four days before the first attempt on his father’s life, when the elder Trump introduced him at a rally in Florida.

When Melania was asked Tuesday if she worries about her husband’s safety, she told the panel of “The Five”: “Yes, I do.”

“If they call him, he is a threat to democracy. Let us ask ourselves: who is really interested in democracy?” she said. “They continue to file lawsuits against the former president, and try to silence him as well.”

“It’s a toxic atmosphere,” Melania added, later insisting her husband’s critics had misjudged him.

“He’s very warm, he’s fun,” Melania said of her 78-year-old husband. “He is very passionate about this country. … He wants to make this country safe so that everyone can have a job and enjoy family life.”

Slovenian-born Melania’s appearance in ‘The Five’ coincided with the release of her memoir of the same name, which hit shelves on Tuesday.
