Objective This study examines thematic content and discourse surrounding multiracial socialization between Black and non-Black multiracial families on multiracial mommy blogs.

Background Mommy blogs have been recognized as a medium through which mothers challenge dominant representations of motherhood, create community with other mothers, and seek out advice. But little is known about how mothers write about and discuss race, racism, and multiracial socialization online. This study addresses this knowledge gap by analyzing how a niche of bloggers—mothers to multiracial children—construct narratives surrounding race, multiraciality, and multiracial socialization online and how their narratives differ by the racial makeup of the blogger's family.

Method Using a MultiCrit framework, this study analyzes 13 mommy blogs written by mothers of color with multiracial children. Blogs were analyzed for thematic content related to race, racial identification, multiraciality, and multiracial socialization.

Results The findings demonstrate that mothers' orientations to multiracial socialization vary depending on whether the blogger has Black or non-Black multiracial children. Bloggers who are mothers to Black multiracial children blogged frequently about their engagement in safety socialization, whereas mothers with non-Black multiracial children did not.

Conclusion The stark difference between thematic content from bloggers with and without Black multiracial children highlights the differing experiences among Black and non-Black multiracial people, for mothers of Black multiracial children, and the implications anti-Black racism has on family processes.
