Of the record millions of people who participated in the historic Women’s March on January 21,2017—in  Washington DC and all around the globe—many were children. Even more children helped from the sidelines—lettering homemade signs, painting t-shirts, knitting hats, and cheering on their adults. But how do we adults, their models, help kids understand the purpose of marching for a cause?

I wrote WHEN WE MARCH to answer this question. Peaceful protest is not just something to learn about in our history books (though that is really, really important too!).

Every child deserves to know that her voice matters, that her neighbor’s voice matters, too—and that not every child has an equal opportunity to make that voice heard. We’re all in this together!
