This study explores the literacy and social practices of a young Omani emergent bilingual child who is beginning to develop bilingualism and biliteracy in Arabic and English through social interactions. One case study of a four-year-old child and her family living temporarily for her father postgraduate studies in Canada is presented. Framed on socio-cultural understandings of literacy development, the study discusses the role of multimodal home practices in the emergent biliteracy development of the child and generates new understandings about children's social practices that are embedded in their daily lives. The study also explores the role of these cultural practices in navigating between two systems of language and culture. The findings make visible how children's engagement with the social context of home, whether physical or through digital media, can enhance their biliteracy development.
