Barron Trump has a considerable age gap with his half siblings, but has built solid relationships with his sisters. She may have overlooked her younger brother turning 19, but Tiffany was sure to shout him out on other birthdays. In March 2019, when Barron entered his teenage years, she took to Instagram to share an adorable snap of the two. “Happy Birthday, B!,” she wrote in the caption. It was a two-slide post, and the first photo was a pic of her and Barron cheering together at what looked to be a political event. The second slide was a group shot of Donald Trump and his kids. The following year, Tiffany uploaded another two-photo post to Instagram on her younger brother’s birthday. That time around she joked about Barron’s immense growth spurt over the year. “Happy 14th birthday to the best “little” brother I could ever ask for!” Tiffany wrote in the caption. Prior to his 19th birthday, Ivanka Trump did not usually give bday shoutouts to her little brother, but she did post a viral video of Barron as a youngster. The whole family was on hand when Donald was officially going into office for his first term in January 2017. A video captured Barron in the background playing peek-a-boo with Ivanka’s daughter. “My youngest brother proves he’s a baby whisperer — while my father signs his first executive orders,” Ivanka wrote on X, formerly Twitter alongside the clip.
