Objective: To apprehend nurses' conceptions and experiences about actions of child health promotion in family health units.

Methods: Exploratory study, with thematic content analysis of statements, obtained through semi-structured interviews with 11 nurses from a municipality in São Paulo.

Results: Three thematic categories emerged on child health promotion actions: they must be contextualized, provide for comprehensive care, and aim at self-care; they are carried out through health guidelines shared by professionals with children and their families, inside and outside the health units; present challenges to be overcome by health services, such as lack of involvement and appreciation of the family regarding child follow-up.
