It is well established that the amount of time children spend playing reflects on their learning, quality of exploration, and relationships. However, little is known about what the main benefits for adults are. In this study, we explore the association between the adults' daily time spent playing with their children (in minutes) and the adults' quality of interactive behavior and their amount of verbal behavior. Participants are 19 mothers, 17 fathers, 22 female preschool educators, 20 male educators, and 78 children (between 3 and 5 years old). Parents and educators were observed during a joint activity with a child. Results indicate that adults who spend more time playing with their children are more empathic, engaged, reciprocal, and changeling. Moreover, parents were also more positive in their communication with children. This research suggests that play offers individual and dyadic learning to children and adults.
