The role of outdoor play provision has been made central in recent years by the Scottish Government as part of the broader expansion of Early Learning and Childcare (Scottish Government, 2017a; Scottish Government, 2017b; Education Scotland, 2019c; Scottish Government, 2020a). This enhanced focus raises questions around how children form their subjectivities in such spaces and how this may differ from what is known about subjectivity within conventional indoor provision. Further, while the existing knowledge base on subjectivity in childhood is derived mainly from the intellectual progress made through the fields of social constructionism (Foucault, 1978), performativity theory (Butler, 2004; 2006; 2011) and developmental psychology (Piaget, 1948; 1957), concerns have been raised regarding the extent to which such frameworks may give primacy to the human, and the logics of humanism, over and above the non-human world (Barad, 2007; Dolphijn and Tuin, 2012; Braidotti, 2013). Such concerns warrant special attention in relation to entirely outdoor environments, where these approaches may underplay the significance of ontological and ontogenetic matters that contribute toward the formation of subjectivity. This study applies a sociomaterial metaphysical framework to propose an alternative way of understanding how subjectivities come to form in early childhood environments, bringing together Spinozist (2002) monism and insights from process philosophy (Massumi, 2002) in relation to Deleuze and Guattari's (1987) concepts of the assemblage and affect. Methodologically, a ethnographic approach, inspired partly from the postqualitative field of scholarship, is employed to gather data on children's subjectivities at Wood Fire, a fully outdoor early childhood setting. The findings of this study reveal the novel materiality and relationality of fully outdoor early childhood provision through which subjectivities are informed , and also point toward the ways that social and cultural determinacies continue to affectively orientate children's desires in the absence of clearly demarcated material spaces. Thus, these findings a demonstrate more expanded understanding of how we, humans, are produced as individuals in specific encounters through processes of 'affective sociomaterialisation'. Through the presentation of data in textual, visual and cinematic modes, practitioners are encouraged to re-evaluate the role of outdoor provision through a sociomaterial metaphysics that challenges conventional knowledges about how children's subjectivities are formed. Practically, this carries implications for how the materiality of outdoor environments is understood to contribute to the child's sense of self on more expansive terms. iii
