This collaborative article explores child-centredness as a theoretical and methodological concept by asking what it means to centre children in research. The collaborative format offers a heterogeneity of voices on the concept as the contributing authors write, critically and creatively, from a range of different interdisciplinary research perspectives. Writing from the departure point of the key role of child-centred approaches within the field, including recent discussions concerning the need to decentre children/childhood, the goal is to spur and contribute to discussions on the possibilities and challenges of the concept, as well as new ways of approaching it.
