Relatively little psychology research has investigated racial-ethnic socialization processes in multiethnic-racial families despite the fact that more than 1 in 7 children born in the United States today have parents from different ethnic-racial backgrounds. The present study seeks to contribute to the extant research by exploring how parents in multiethnic-racial families seek to help their children access and benefit from two (or more) sets of cultural assets. Accordingly, this study considers key themes about cultural socialization that emerged in qualitative interviews with parents in multiethnic-racial families (n = 37). Key themes emerging from these interviews included the importance of both co-parents: (a) putting in the time and effort to learn about each other’s cultures and cultural practices; (b) being reflective about the practices, values, and traditions that were and were not important to them to share with their children; and (c) protecting their children from racial micro-aggressions in a variety of settings by advocating for the recognition, inclusion, and appreciation of their children’s multiple ethnic-racial heritages. There is such a paucity of research on cultural socialization approaches in multiethnic-racial families that these perspectives from parents offer both valuable building blocks for future research efforts as well as practical guidance to the growing number of multiethnic-racial families in the United States and elsewhere.
