Mothers' marital adaptation following the birth of twins or singletons: empirical evidence and practical insights.

Parenting twins is typically portrayed as more stressful than is parenting single children and, therefore, more of a strain on the marital relationship. With this in mind, the present study examined the contribution of infant characteristics and mother's internal resources (attachment style) and external resources (maternal and paternal grandmothers' perceived support) to their marital adaptation during the first month following delivery, comparing mothers of twins (n = 88) with mothers of singletons (n = 82). The findings indicate that both internal and external resources contribute to the marital adaptation of the two groups, even beyond the contribution of specific circumstances. Thus, it seems that the birth of twins and the birth of a single child are normative life events that have more in common than previously acknowledged. The implications for the focus of social work interventions, particularly in the case of the birth of twins, are discussed.
