This paper applies a posthumanist lens, informed by the work of Hollett and Ehret and of Ingold, to consider children’s playful affective entanglements with the human and the more-than-human during fluctuating periods of social distancing in the COVID-19 pandemic. Through this refracting theoretical lens, I (re)examine a selection of play and leisure experiences of an emergent subject – the pandemic child – during the national U.K. lockdowns of 2020 and 2021. Via a national online, qualitative survey, children and families were invited to share examples of their play and leisure experiences during the pandemic to the Play Observatory, a U.K. research project that ran from 2020 to 2022. These survey contributions provide portals through which to (re)consider children’s connection, participation and emergent becomings, attuning analytical attention towards children’s affective place-event entanglements during pandemic times. A posthumanist (re)telling of children’s Play Observatory contributions demonstrates how children were imbricated in constantly emergent affects, meanings, becomings and potentialities, that waxed and waned, intensified and dissipated, transcending the physical locus of lockdown. This paper contributes to the field by unsettling discourses of rupture, loss and deficit that have tended to dominate public and policy discussions of children’s experience of lockdowns. It contributes to ongoing, collective attempts to interrupt policy responses to the pandemic that centre individualising practices of curriculum ‘catch-up’ and fail to invite into the debate consideration of the potential richness of experiences and events encountered by the pandemic child outside of the strictures of normal schooling and curriculum.
