This chapter argues that parents have a moral duty to provide good care. This standard is richer than adequacy but less demanding than best care. Grounded in Kant’s account of imperfect duties, good care involves emotional attentiveness, responsiveness and support for a child’s flourishing. The chapter also explains the internal limits of this duty, drawing on Marmor’s critique of absolutist rights, and explores the relational nature of good care as shaped by love and vulnerability. While not legally enforceable, good care is a genuine moral obligation rooted in the structure of the parent–child relationship.
