See Drew Barrymore's Daughter and the Other Inspiring Children at the Women's March

In the aftermath of the Women's March on Jan. 21, it has been estimated that over four million people attended the historic demonstration. While the signs ranged from powerful and inspiring to hilarious and meme-worthy, our favorites came from the many children who participated in the peaceful march.

Although some of the smaller children who attended may not have been able to understand the significance of the event, they nonetheless got creative with colorful doodles. One sign, for example, simply said, "Happy March." Others were more politically advanced and featured messages on girl power and the future.

Scroll ahead for some of our favorites, including Drew Barrymore's 4-year-old daughter, Olive.
