This article explores children in the majority world’s experiences of the stringent health security practices implemented in response to the COVID-19 pandemic. Drawing on original empirical research in five majority world countries, it examines children’s own accounts of their experiences of lockdowns and stay-at-home orders. Our analysis of the children’s narratives draws out the spatial, temporal, and affective dimensions of home-making under stay-at-home orders. In turn, we highlight complex and ambivalent connections between the notable and the mundane, between security and the everyday, and between home-making and world-building, and offer conclusions informed by majority world children on the ‘(important) banality of security and security politics’.
