Examining the critical potential of everyday practices within early childhood spaces, this article builds on a growing body of pedagogical research that challenges researchers 'to use theory to think "with" data' and create new concepts that are born out of the possibilities of the theory-practice relationship. By aligning Deleuze and Guattari's theory of immanence with the concept of 'an attitude of research', it is argued that an inherent quality of this concept is that it is shaped by the subjectivities, values and processes of children's spaces. It is in the critical potential of one's engagement with "quotidien" practices that the identity of an attitude of research is created. By identifying the aesthetic qualities that guide interactions, visibility is brought to the patterns of thinking that are contextual and therefore unique to an early childhood space. This article demonstrates that practice and an attitude of research constitute one another, creating a new theory -- 'research as lingering' in the threshold of the everyday.
