While temporality has been addressed in the context of child welfare, the temporal dimensions of differentiation and othering remain unacknowledged. This article draws on material from a Swedish child welfare agency and is theoretically inspired by postcolonial and queer theories and critical childhood studies. It is based on an analytical juxtaposition of care order applications recommending immediate child welfare interventions versus interventions that are recommended after long ongoing assessments. Such interventions are addressed as unequal in terms of timing. The article discusses temporal themes related to permanency verus temporary, which guide assessments of changeability. I show how immediate interventions respond to chronicity - the temporality of incurability, permanency, and underdevelopment. However, social problems in long ongoing assessments are assessed as permanent only after long ongoing observations or passage of time. The article discusses how ideas about change reproduce wider societal and intersecting inequalities. This becomes visible when considering time as allocated to parents and their potential to bring about change. I argue that even though permanency differs from chronicity, it still limits a discussion about change as societal, and the detection of problems remains within a developmentalist neoliberal framework. In the conclusing remarks, I offer an alternative reading of allocated time that can manoeuvre developmentalist logics, while balancing responsibilisation between the individualn and the society.
