Make Kids a Part of the Story
In addition to telling kids about your own experiences, you can also use storytelling to explain the history behind systemic oppression. Just remember that, in doing so, it's also necessary to show your child what their role in the story is, whether systemic oppression has resulted in their privilege or been used against them. According to David Nurenberg, Ph.D., an associate professor of Education and author of "What Does Injustice Have to Do with Me?", as you make your way through a story, you should try pointing out where your children might share a common experience with someone else.
Once you help your kids come to this realisation, they can then start to understand whether or not this unjust treatment was amplified by larger institutions, and it may also help white children empathize with the experiences of BIPOC.
