This article makes a connection between narrative ethnography, childhood studies and new materialist theories in studying children's perspective on school. It presents "children writing ethnography" as an approach based on complexity and involving participatory research. The question of "what is happening in the classroom" is explored through writings produced in class by 10-year olds. The "messy" ethnographic data are examined within the framework of narrative ethnography using the idea of "small stories" that capture everyday interaction. Furthermore, both material and embodied meanings in the writings are discussed. New materialist theories and the idea of "nomadic" make it possible to account for the connectivity between the writings, the classroom reality, the child-ethnographers and the research, which are seen as mutually producing one another. The author suggests that engaging with children's free-flowing ethnographic writing serves as a productive way to conduct participatory ethnographic research, as well as to investigate contemporary childhoods in all their complexity.
