Research Findings: This study examined the unique and relative contributions of mothers' and fathers' parental control and coparenting to toddlers' committed compliance with parents in both dyadic parent-child and triadic family play contexts. Sixty-eight mostly middle-class, 2-parent families with toddlers (16-37 months) were observed in a university laboratory setting. There were positive associations among mothers' gentle guidance, balanced coparental engagement, and child committed compliance with mothers. However, there was no association between any parental control or coparenting variable and child compliance with fathers. Unique contributions of fathers' control and coparenting, beyond mothers' parenting, were found for children's compliance with mothers but not with fathers. Practice or Policy: The findings highlight the importance of taking the family relationship context into account when assessing parenting behaviors and toddlers' compliance. (Contains 4 tables.)
