Decision‐making by families and professionals about how to support children's development is an integral aspect of home visits. This study investigated home visit decision‐making in a US program for families experiencing poverty, Early Head Start (EHS), through the following questions: What types of decisions do home visitors and families make about children's development during EHS home visits? How and to what extent do home visitors and families participate during these decisions? A convergent mixed methods research design was implemented to investigate participation through frequency counts and discourse analysis of home visit transcripts. Home visitor participants were four women, three white and one Black. Twelve families participated (12 mothers, 2 fathers). Parents identified as white (n = 8), Black (n = 3), and multiracial (n = 3; Black and white). One parent was a bilingual Arabic and English speaker. A total of 66 decisions about children's development were identified, with 49 decisions initiated by home visitors and 17 initiated by families. Although families talked more and took on active roles when they initiated (i.e., opened) decisions, home visitors predominantly controlled decision‐making. Quantitative and qualitative participation differed only in the beginning of family‐opened decisions, and home visitors gradually took more control.
