This article employs a sociomaterial perspective and explores how material artefacts take part in the enactment of social norms by analysing empirical examples from two different childhood studies projects in Norway. Drawing on interview data with tweens, (children aged 8–12), and observational data from an early education and care institution (ECEC), we argue that material, in this case toys and makeup, make a difference in the enactment of social norms in children's everyday lives. Our aim is to demonstrate the malleability of a sociomaterial perspective and show how this can lead to new insights and open childhood studies as a field.
