Reading identities are the ways that a child constructs the self as a reader across contexts and time. This study examines the impact of language contexts on the reading identities of multilingual children. Participants were ten prekindergarten children participating in a Chinese-English family literacy programme with a parent or grandparent. Participants read Chinese and English language books across English, Chinese and multilingual contexts. Children's reading identities were examined across language contexts to explore the interplay between language contexts and reading identities. Findings describe convergences and differences in reading identities across contexts for Chinese, English and multilingual language use and Chinese and English texts, and provide insights into the ways that different language contexts for reading affect multilingual children's early reading identities. Multilingual contexts appear to provide key spaces for the development of reading identities, and English and Chinese contexts contribute to unique aspects of children's reading identities.
