Belonging is emerging as an important concept in contemporary early childhood curricula, and calls have recently been made for belonging to be critically interrogated and further theorized. This article explores how belonging was operating for an infant in Australian family day care by looking at an episode that took place between the infant, a group of older children and the educator. The concepts of assemblage and desire from Deleuze and Guattari are used to problematize the episode and see something new. The complex and unresolved nature of belonging and infants’ roles and capacities within the politics of belonging are discussed. The paper attempts to stretch our thinking about how belonging operates for infants and the possibilities for theorizing belonging in early childhood education and care.
