In relational ontologies, care is considered as relationally constructed in practices. It is thus important to understand how caring relationships are produced. However, there are different ways of producing these caring relationships. This article contrasts the production of caring relationships in a logic of substitution and in a logic of care in a home-based strengthened educational childcare service. While most studies focus on the implications of different models of care for carers-carees dyadic interpersonal relationships, this study also considers how the design and use of tools, as well as relationships with third parties involved in care practices, differ within these two logics. This study also shows that they imply different temporal conceptions and orientations.
