In this paper we conduct a poststructural discourse analysis inspired by Carol Bacchi's 'What's the problem represented to be?' (WRP) approach. We explore what kinds of problems are formulated in preschool educational policy on multilingualism, and what underlying assumptions underlie the dominant discourse on language proficiency in Sweden. Serving as a case to discuss how racism, ableism and childism intersect with linguicism, we examine the importance of shifting from a 'children's (special) needs' discourse to a 'children's (language) rights' discourse through a social justice education framework. We draw upon Elisabeth Young-Bruehl's understanding of childism, which refers to prejudice and discrimination against children based on beliefs about their inferiority to adults. The right to and rights in education are contingent upon linguistic rights, upon students learning to use their first language, whether that be minority, indigenous or sign language.
