How do we create and maintain age-inclusive structures of support and mutual aid in social justice movements and communities? There are many books on parenting, but very few that give nonparents tools to become better allies to caregivers, parents, and children, and to build organizations and communities that welcome and include all ages. Don’t Leave Your Friends Behind is an invaluable collection of personal stories and concrete examples of how to increase community support for families, featuring a wide array of voices. Let’s build an all-ages, inclusive revolution that leaves no one behind!
