This paper begins with a discussion of some of the key insights of recent sociocultural research that consider bilingual children and learning to read and culminates in a discussion of Syncretic Literacy Studies (SLS). It then presents data from an ethnographic study that focused on the learning experiences of a small group of Year Three Bangladeshi-heritage pupils during 1 year of their schooling in order to problematise some of the claims made in recent sociocultural work and in SLS, particularly the focus on children's agency. The findings from the study suggest that (a) there are limits to children's agency that are not recognised in recent work and in SLS; (b) that identity has an important role to play: children can successfully mask what they cannot do as readers in order to present a particular identity in the mainstream classroom; and (c) that the access some children have to mediators may be limited and can change over time.
