This article investigates children’s participation and sense of belonging from the perspective of unaccompanied children, based on two qualitative research projects with unaccompanied children in Sweden and Finland. The results show that the unaccompanied children’s own understanding of their participation and belonging in different positions was fluid; for instance, the borders between childhood and adulthood, and striving for independence or wanting to be cared for by adults were flexible, allowing the children’s movement within and between the categories.
