Interaction behavior of infants and their dual-career parents

The behaviors of dual-career parents were compared in face-to-face interactions with their 8-month-old infants who attended on all-day infant nursery. Mothers, as compared to fathers, exhibited more frequent smiling, vocalizing, and touching with their infants. In turn, the infants spent a greater proportion of the interaction time smiling and being motorically active when they were interacting with their mothers versus their fathers.
