The COVID-19 pandemic posed major challenges for the lives of children in terms of school closures, loss of routine, reduced social contact, bereavement and trauma. The pandemic also gave rise to a focus on play as a fundamental support for children's wellbeing. This study examined early childhood teachers' reported practices of using play upon returning to school in Ireland after lockdown restrictions which included a 6-month period of school closures. Building on previous research on play in early childhood education during the early stages of the pandemic, 12 primary school teachers in early childhood classrooms (children aged 3-8 years) participated in focus groups aimed at exploring teachers' experiences of using play upon returning to in-class teaching. Through reflexive thematic analysis of the focus groups, four themes were identified that encapsulated teachers' experiences: play in the classroom embodied similar characteristics and qualities during COVID-19 as before the pandemic; play was considered a priority in early childhood education classrooms; teachers planned carefully for facilitating play in the classroom in response to COVID-19 regulations; teachers' noted the importance of the social and relational components of play for children in the context of COVID-19 regulations. For educational policy, these findings highlight play as a 'go-to' strategy by teachers for supporting children in formal education during a pandemic and suggest play is a well-established context that can be used in educational policies to support children's learning, especially during and after times of crises.
