This article explores Indigenous Mexican mothers' perspectives on multilingualism and Indigenous language maintenance in their children's lives. Drawing on interview data from a larger qualitative study of language and ideology among multilingual children in Los Angeles, California, the article examines the perspectives of four Zapotec mothers who have children in a local public school with a Spanish-English dual language program. The interview data highlight what these women "think" and "do" with respect to the maintenance of the Zapotec language in the lives of their school-aged children. Critical Latinx Indigeneities and the feminist notion of "linguistic motherwork" are used to highlight the intersectional nature of these women's efforts to construct and sustain indigeneity in diaspora.
