The hypothesis that qualities of emotional availability in mother-twin dyads serve an organizing role for children's relatedness with others was explored. Mothers were observed in dyadic interaction with their three-year-old twins during semi-structured play at home. Both maternal and child dimensions of emotional availability were scored by independent observers and related to tester ratings of several features of the children's relatedness to the testers during the home visit and to maternal reports of the children's prosocial tendencies when their siblings were in distress. Findings supported the suggestion that individual differences in emotional availability were meaningfully related to preschool children's behavior with others.
