Baby Theodore may have been too young to hit the polls, but he couldn't be happier that his grandpa, Donald Trump, won the presidency.

Donald's eldest daughter, Ivanka Trump, took to Instagram on Wednesday to celebrate her father's win with a video of Theo cheering in a red Trump shirt.

With her father newly elected, it seems Ivanka has a lot of work to do back at her fashion line, which has recently been boycotted by women protesting her father's values. The 35-year-old designer addressed the controversy during an interview with ABC News last month, saying that people are simply free to do as they please.

"The beauty of America is that people can do what they like," she explained, "but I prefer to talk to the millions, tens of millions of American women, who are inspired by the brand and the message that I've created."
