RESUMEN
Consistent, sensitive caregiving across home and childcare contexts supports optimal development. In this paper, we share the story of the development of Hearts and Minds on Babies (HMB) for Early Head Start (EHS) administrators, teachers, and parents. HMB was designed to support caregiver reflective functioning and sensitivity and reduce caregiver stress. This paper describes a series of Plan-Do-Study-Act cycles used to adapt an existing parenting intervention into the HMB programming for EHS. Throughout the paper, we present HMB concepts and learning objectives and share teachers' and parents' feedback and adaptations to content and delivery options that support implementation by EHS programs. Feedback from the final cycle suggests that HMB supports EHS administrators, teachers, and parents in their roles and improves relationships. The paper highlights the importance of research-practice partnerships in developing programming that meets the needs of EHS.
