Families engage in a range of cultural practices in their everyday lives that shape children's early literacies. Given the growing number of children who are living outside the country of their birth or their parents' birth, more research is needed to highlight the under-recognised literacies of young children shaped by their family cultural practices and immigration experiences. This year-long qualitative study in an Aotearoa New Zealand playgroup explored how newly settled families worked to sustain their cultural practices and supported their young children's understandings of new cultural norms in the context of immigration. Qualitative data collection methods included participant observation in the playgroup and photo-elicitation and semi-structured interview conversations in family languages. Findings highlight family aspirations and tensions regarding children's participation in family cultural practices over time, sustaining family languages once children transitioned to school, and notions of belonging. Family participation was integral to interpreting children's meaning-making in the playgroup, including how children flexibly navigated language differences and unfamiliar cultural practices. This study highlights the importance of learning from families about the linguistic and cultural resources young children draw on to represent, communicate and belong in a new country.
