Grandparents play a significant role in childcare and one activity that frequently occurs within this context is story-reading. However, relatively little attention has been given to the potential part that grandparents can play in terms of language and literacy development of young children. This article reports on work investigating the interlingual and intercultural exchanges occurring in a home setting in East London. In particular, it focuses on how the traditional heritage pattern of story and rhyme reading by a grandmother of Bengali origin is fused with practices experienced by her six-year old grandchild. The data reveal not only the multiple worlds inhabited by the grandchild during story-reading but also the syncretism of these worlds on a number of levels. This article contributes to the small but growing body of investigation into the reading styles occurring within families from different cultural backgrounds. (Contains 5 figures and 4 notes.)
