In the current anti-immigrant context, Latinx families, children, and communities experience language as a highly contested and surveilled practice with consequential effects. In this study, I drew on the concept of literacies of surveillance and translanguaging to examine how language was embodied and rationalized in the context of three homes of Latinx, transfronterizx families. This critical multiple-case study led to three main findings: (1) Parents and children are linguistic guardians and surveil from a place of love and care, (2) embracing Spanish-English parallel monolingualism is a form of "respeto," and (3) translanguaging is a way of being for bilingual children moving in and out of surveilled moments. The findings have important implications for reconstructing the concept of linguistic surveillance in research and reframing parents' and children's roles in school when it relates to designing and authoring children's bilingual futures.
