President Donald Trump’s eldest daughter Ivanka Trump and son-in-law Jared Kushner have moved to Washington, D.C., to be closer to the White House, where Kushner has taken on the role of adviser to the president.

As the couple shifts base with their three children, here is all you need to know about the Kushner kids who make routine appearances on their mother’s Instagram account.

Arabella Rose Kushner

Ivanka and husband Kushner’s first child after their marriage in late 2009, Arabella was born July 17, 2011. She is Trump’s third oldest grandchild, after Donald Trump Jr.’s children Kai Madison and Donald Trump III.

During the Lunar New Year celebrations, she shot to fame in China after a video posted by her mother on Instagram went viral on social media. Arabella, 5, could be seen playing with a traditional Chinese puppet as she sang in Chinese.

Joseph Frederick Kushner

Joseph was born Oct. 14, 2013, and named after his paternal great-grandfathers, who Ivanka described as “master builders of their generation and inspiring patriarchs of their families.”

The 3-year-old shares great camaraderie with his toddler brother and has made public appearances with his parents. He seems to be musically-aligned, just like his sister, and was spotted singing “My Favorite Things” from “The Sound of Music” on social media.

Theodore James Kushner

The youngest member of the Kushner family was born March 27, 2016, in the midst of the presidential election campaign. Spotted routinely on Ivanka’s social media accounts, usually flanked by his older siblings, Theodore was recently captured crawling in the White House, a moment that his mother called an “incredible” milestone.
