Although research in health care suggests that one of the most important factors for efficient medical delivery is the child's willingness to cooperate, little is known about how caregivers facilitate cooperation with young children during medical treatment. In this article, we explore interactions between parents, nurses, and young children during pediatric nebulizer treatment in terms of tact as a pedagogical concept. Based on our analysis, which followed a hermeneutic approach and included video observations of five hospitalized children aged between 15 and 30 months, we present four themes related to pedagogical tact of caregivers and children's willingness to cooperate, and discuss the role that medical products can play in this cooperation. The results benefit pediatric health personnel, as well as product designers.
