Canada receives over 30,000 refugees each year, approximately 10% of whom are under five years of age. While to varying degrees the factors influencing the experiences of adult refugees have been identified and researched, the experiences of young refugee children "living in-between" has only recently begun to capture researchers' interest. This article considers what the experiences are of young refugee children in their day-to-day living between languages and cultures as they make a transition between home and Canadian early childhood settings. More specifically, the question addressed is: What roles do refugee children play in mediating the host culture for their parents in the hybrid place created by play? The authors propose that play in early childhood does serve, for refugees experiencing resettlement, as a site of cultural mediation, contestation, and identity negotiation. An analysis of three Sudanese refugee mothers and their four-year-old sons' use of common early childhood artefacts--wooden building blocks--is used to demonstrate how young refugee children who experience child care outside their home for the first time not only learn to "be a preschooler", but learn to "interpret" this role to their parents.
