Different social experiences help children develop distinctions between domains of norms. This study investigated whether mothers respond differently to moral, prudential, and pragmatic norms during the 2nd year, a period that precedes the time when children are able to make explicit distinctions between these norms. Sixty mothers of infants between 11 and 23 months were interviewed. Mothers' reports of their initial interventions, changes in intervention following noncompliance, and emotional reactions depended on normative domain. Initial interventions were less differentiated by domain for mothers of older than for mothers of younger children. These findings suggest that children have social experiences in the 2nd year that are associated with distinctions among normative domains.
