peer reviewed ; There is a consensus that home languages are the foundation on which to develop additional languages and that collaboration between homes and institutions of early childhood education and care (ECEC) can contribute to the development of children’s language and literacy skills. Nevertheless, educators seem rarely to draw on multiple languages in literacy activities. Furthermore, situations where educators and parents jointly read to children are scarce. Luxembourg, which has implemented a programme of multilingual education in ECEC, is an ideal context to investigate literacy practices and language use of educators and parents. Drawing on observations in two multilingual centres in Luxembourg as well as interviews, the present study examines the interactions between the educators and the three-year-old children and those between the educators, parents, and children when the parents occasionally read books in the centres. The findings show that the educators in both centres used several languages and that the types of interactions differed. When the parents offered literacy activities, their use of languages and the roles they played also differed, varying from being fully involved to taking a marginal role. The findings can help educators and policymakers develop inclusive and participatory literacy practices which actively involve children and parents.
