The nano-field: Theorising ethical tensions at the intersection of institutional rules and child-centred research

Early childhood research increasingly foregrounds children’s participation and complex agency, yet ethical tensions persist when child-centred research unfolds within adult-governed pedagogic institutions. These tensions often arise in fleeting interactional moments where participation redistributes authority and unsettles institutional norms and peer hierarchies. Drawing on data collected in 2016 with 18 children aged 3–5 across two London nurseries, this paper analyses two research encounters involving peer conflict and exclusion. The findings demonstrate that research participation can recalibrate symbolic capital within pedagogic settings, enabling children to negotiate, stretch, and at times subvert institutional rules in real time. These moments are ethically intensified because the researcher’s positioning simultaneously softens and reconfigures adult authority. To theorise this hyper-local dynamic, I introduce the concept of the nano-field; a nested research field within broader pedagogic and institutional fields where capital, hierarchy, and rules are renegotiated. In dialogue with my earlier work on agile agency, the nano-field specifies how children discern rules through situated co-reflexivity, embody research identities, and reconfigure peer hierarchies. The paper concludes that without theorising the research encounter itself as a nested field, ethical dilemmas risk being reduced either to procedural ethics or to celebratory accounts of agency. The nano-field therefore constitutes a necessary refinement of field theory and offers a framework for ethically responsive child-centred research in early childhood settings.
