Children’s nurturant interactions with their infant siblings: An exploration of gender differences and maternal socialization
In this study, 20 families with two parents, an infant under the age of 1 year, and one or two older siblings between the ages of 4 and 7 years, were observed in their homes. Each family was observed four times at approximately monthly intervals. Only data from the last three observations were reported. Two issues were being studied: gender differences in the interactions of the older child with the infant, and maternal socialization of the older child's nurturant interactions with the infant. Older girls interacted more with their infant siblings, particularly in a nurturant manner. There was virtually no evidence of direct maternal socialization of this gender difference.
