It's like he waited to make it as grand a moment as possible!

Ivanka Trump's son Theodore stole the spotlight from his President grandpa yesterday by crawling for the first time, and the milestone went down on the living room floor of the White House! The 35-year-old businesswoman documented her little man on the move in an adorable Instagram video, as his big sis Arabella looked on in amazement.

"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!” The Donald's daughter captioned the clip.

The First Family relocated to Washington D.C. so Ivanka's husband Jared Kushner could begin his position as senior adviser to the new POTUS, and they seem to be loving life at 1600 Pennsylvania Ave.

We're glad they're so happy, because women, gays, minorities, and pretty much everyone other than old white men are already terrified of what's to come with this administration!
