'Big night for baby Theodore,' Ivanka Trump wrote in Instagram Friday, referring to her youngest child. 'He took his first steps!' With it, she posted a video of President Donald Trump's grandson Theodore excitedly entering the world of being bipedal. Big night for baby Theodore. He took his first steps! A post shared by Ivanka Trump (@ivankatrump) on May 18, 2017 at 3:30pm PDT Trump converted to Orthodox Judaism before marrying husband Jared Kushner in 2009. Ivanka and Jared even hosted a Shabbat meal for the president's cabinet in January in their home in the Kalorama neighborhood of Washington, DC. Her social media presence has brought a touch of family to the new administration's image. In March, she posted a photo of baking traditional Purim treats with her children, Arabella and Joseph.

The first permit was to ride in the motorcade for her father's inauguration, and the second comes as the couple boards Air Force One to join the president on his foreign tour, which will include a stop in Israel. Air Force One has reportedly stocked kosher food in deference for the couple.
