Ivanka Trump shared an Instagram video of her 10-month-old son Theodore crawling for the very first time.
But unlike most 10-month-old babies, Theodore's first crawl occurred inside the White House.
"There were so many incredible milestones this past weekend -- including one for baby Theodore who crawled for the very first time in the White House!" Ivanka wrote on Instagram.
Ivanka's five-year-old daughter Arabella is seen in the video (above) coaxing baby Theodore along with encouragement.
Ivanka Trump and husband Jared Kushner have three kids. Arabella and two sons; 3-year-old Joseph and Theodore. The 35-year-old businesswoman often shares cute snaps of her children on social media.
A video of Arabella speaking Mandarin and reciting poetry for the Lunar New Year went viral in China last year.
The family reportedly moved to their new D.C. home Monday after spending a few nights at the White House following the inauguration.
