Melania Trump is set to arrive in the United Kingdom on Wednesday alongside former President Donald Trump for their second state visit. Their son, Barron, will not be joining them this time. Instead, he will remain in Washington, D.C., where he has just begun his sophomore year at NYU’s Stern School of Business.

According to a source speaking to People magazine, Melania is said to be quietly worried about her son as he adjusts to new routines and growing independence.

Barron Trump spent most of his childhood inside Trump Tower in Manhattan, where Melania made it her personal mission to protect him from public scrutiny. Even after the family moved to the White House during Donald Trump’s first term, she continued to shield Barron from the spotlight, keeping his life as private and normal as possible despite the extraordinary circumstances.
