In this paper I explore the possibilities of investigating the everyday spaces of infants and young children. Overall infants and young children have been overlooked as research partners in critical geographies and social studies of childhood. The marginalisation of infants and young children as agents in research reflects earlier concerns about the neglect of children in sociology and human geography. Where infants have appeared in sociology or human geography, they have tended to be constructed as ‘objects of care’ (e.g. in feminist research) and/or ‘objects of analyses’ (e.g. within population geography). In this paper I argue that exploring the social and spatial experience of infants critiques dominant assumptions about (children’s) agency and can provide fruitful insights into processes of subjectification and the reproduction of embodied inequalities.  I suggest three potential agendas for researching infants, in which I engage in a preliminary analysis, drawing upon ethnographic research in a children’s centre – parent/carer infants and micro-mobilities; moral geographies of specific infant/parent/carer focused spaces; micro-infant geographies, infant agency/subjectivity and subjectification in specific spaces and times; broader socio-economic inequalities reproduced in infant subjectivities : habitus. The penultimate section discusses some of the methodological and ethical complexities of researching with infants, and questions how (and if) these can be overcome.
