This is going to be a thread full of resources for white parents. Literally the only way to dismantle racism is for US to be anti-racist and teach our kids to be anti-racist. If you aren't having serious conversations with them already, getting started might seem daunting.
First up is an Atlantic article about sociologist Margaret Hagerman's research on how white kids learn about race. It is fascinating, and she wrote a book which I will link in the next tweet. (N.B. I have read the article but not the book) https://www.theatlantic.com/family/archive/2018/09/white-kids-race/569185/

This is a wholeass podcast on this exact topic! I have not listened to it yet BUT there is also a free PDF you can download with quick bullet points to help you start a conversation in your family. https://safespaceradio.com/talking-to-white-kids-about-race-racism/
This is a helpful article (from the aptly named site Parent Toolkit, which I am otherwise unfamiliar with) that breaks down why and how we need to talk to our kids and provides additional resources. https://www.parenttoolkit.com/social-and-emotional-development/advice/social-awareness/how-to-talk-to-kids-about-race-and-racism
This is a good 101 with a list of helpful books (please note that I am uncomfortable with the excessive use of quotation marks in the article, but that seems to be unfortunately common in this topic, and the information is good). https://www.readbrightly.com/how-to-talk-to-kids-about-race-books-and-resources-that-can-help/
This is a podcast (again, not yet listened to) with the sociologist from earlier in the thread, Margaret Hagerman. https://drrobynsilverman.com/how-to-talk-to-white-kids-about-race-racism-with-dr-margaret-hagerman/
Here is an article in Time by Margaret Hagerman on why we (white parents) need to be doing more. https://time.com/5362786/talking-racism-with-white-kids-not-enough/
This Washington Post article talks about racism specifically in the context of COVID-19 and what we as white parents should be doing to talk to our kids about it. https://www.washingtonpost.com/lifestyle/2020/05/22/we-need-more-white-parents-talk-their-kids-about-race-especially-now/
This article opens with a personal anecdote about parenting at a playdate when a kid said something racist, and then discusses how she handled it with two experts and passes along their advice. https://www.parentmap.com/article/how-to-talk-to-kids-about-race-racism
This is a list of resources from the Center for Racial Justice in Education, and honestly I could have just linked to this in the first place but I know you like options. https://centerracialjustice.org/resources/resources-for-talking-about-race-racism-and-racialized-violence-with-kids/
That's it for now, but I will return as I find other resources. Please do not ask your Black friends for help on this. The resources are out there for you to use. I got most of these from a quick Google. You can do this.
