<p>Children newly placed in public care are particularly vulnerable to disruption. Yet, there is notably lack of research and theorization about moves between care arrangements. Drawing on a qualitative case study of a Norwegian care arrangement that combines residential with specialized foster care, this article explores how moves between care arrangements are facilitated and experienced by various carers—including foster carers, parents, foster care consultants, residential staff, and managers—all of whom were interviewed for the study. These moves are analyzed through the conceptual lens of multilayered transitions, with the aim of contributing both empirical insights and theoretical development. The analysis highlights the interconnected and precarious nature of transitions in care, and the importance of flexible timeframes, collaborative practices, and inclusive relational approaches in supporting the child. The article proposes the concept of “supported transitions in care” and discusses its relevance for understanding the processes and practices involved, as well as for promoting sustainability in public care.</p>
