Children with Ivana
Donald Jr., Ivanka, and Eric are Trump's three eldest children, from his first marriage with Ivana Trump.
Prior to the election, each of the siblings held the title of Executive Vice President at The Trump Organization. During the campaign, they served as surrogates for their father on national news programs. Following Trump’s election victory, all three were named to the presidential transition team.
Following the inauguration, Donald Jr. and Eric took charge of the family's real estate empire. Ivanka moved to Washington, D.C. with her husband Jared Kushner, who was appointed to a senior White House advisory position.
Tiffany Ariana Trump (born October 13, 1993) is Donald Trump's only child with Marla Maples. In 2016, she participated little in her father's campaign because she was attending the University of Pennsylvania, her father's alma mater. Shortly after graduating in sociology and urban studies, she made a speech for her father at the Republican National Convention at age 22.
Barron Trump in November 2016
Barron William Trump (born March 20, 2006) is Donald Trump's youngest child and his only child with Melania Trump. He is of German and Scottish descent on his father's side and Slovenian descent on his mother's side. In May 2006, Barron Trump received the Christian sacrament of baptism at The Episcopal Church of Bethesda-by-the-Sea in Palm Beach, Florida. He attended the Columbia Grammar & Preparatory School in Manhattan. Barron is fluent in English and Slovene. During his early childhood, Barron made several television appearances, including on The Apprentice and a May 16, 2006 episode of The Oprah Winfrey Show at only 2 months old. Barron did not immediately move into the White House when his father became president, but remained at Trump Tower with his mother until the end of the 2016–2017 school year. Melania and Barron moved to the White House on June 11, 2017, and he now attends St. Andrew's Episcopal School in Potomac, Maryland.
He made few appearances during the 2016 election because his mother wanted to keep him out of the spotlight.  He made a total of three public appearances on the campaign trail, appearing at a campaign rally in South Carolina, and attending his father's RNC acceptance speech and presidential victory speech. While absent from pre-inauguration events, he was at his father's inauguration ceremony in January 2017 and some of the following events.
Barron is noted to be a fan of soccer, appearing in an Arsenal F.C. jersey and meeting D.C. United players at the Easter Egg Roll. In September 2017, he was selected to join the U-12 team for D.C. United's Development Academy.
