Prior research has indicated that expectant parents overestimate the extent to which fathers will take part in the “work” of parenting, with mothers often becoming disenchanted when these expectations are violated following the baby’s arrival. In this study, we examine the role of violated wishes concerning childcare involvement in accounting for variability in maternal and paternal marital satisfaction, and in early coparenting behavior as assessed during family-interaction sessions. The results indicate possible negative effects of violated wishes on the enacted family process and confirm previous findings regarding the effects of marital satisfaction. In addition, we uncovered differences in the way that violated maternal wishes are related to coparenting during playful and mildly stressful family interactions.
