High-quality and stable child care can be an important support for young children in foster care. Unfortunately, many children are placed in low-quality care and have frequent disruptions to their care. This article describes how early childhood mental health consultation (ECMHC) to child care programs serving foster children can support children and their caregivers. The authors illustrate how system-level ECMHC can support child welfare staff members in their efforts to develop trainings, policies, and practices to increase quality and stability in child care.
