Upon COVID-19 being declared a pandemic by the World Health Organization, parent-carers worldwide faced major challenges in how to adapt, become resilient, and to continue educating their children at all levels amid school closures. Home-schooling, with parent-carers becoming the substitute teachers, had become the new 'norm' during the first and third lockdowns in England. This paper reports on qualitative findings from semi-structured interviews with 35 participants comprised of parents with children aged between 5 and 8 years old in South London, England. Thematical analysis is used to capture parents' well-being experiences of home-schooling amid COVID-19 compulsory school closures. This paper explores how the pressure on parent-carers to provide education at home akin to a school setting is physically and emotionally challenging. The paper also addresses how parents' stress levels intensified in the second (January 2021) home-schooling period. A post-structural feminist framework is deployed to unpick gender socio-cultural inequalities relating to the distribution of work/labour/childcare duties at home during lockdown. Existing research has focussed on the impact on low-income families and children's well-being during the pandemic. This research contributes to existing research by addressing an under-researched area relating to the impact on well-belling for middle-income maternal caregivers. Findings of this research show how financial privilege does not provide an escape from additional stress and how parents' well-being was affected.
