Who Are Donald Trump's Grandchildren? Meet Kai Madison, Arabella Kushner And Their 6 Cousins

After the lengthy 2016 campaign cycle, you're probably familiar with Donald Trump's children. There's Ivanka and Tiffany, the gorgeous daughters from different marriages, Eric and Don Jr., who will take over their father's businesses while he's in office, and Barron, the rarely seen 10-year-old attending an elite school in Manhattan. You know their faces, and you probably even follow most of them on Twitter.

But what do you know about the new president's grandchildren? There's eight of them, according to the American Grandparents Association. Get to know the youngest members of the new First Family below.
