coparenting
n. the practice by which parents coordinate their child-rearing practices. It can be supportive in nature, with partners reinforcing one another in child-rearing activities, but it may also be antagonistic, where partners are either inconsistent in parenting (e.g., show discrepant levels of parent–child engagement) or undermine each other’s child-rearing efforts (e.g., compete for their children’s attention or conflict about their children). Also called parental alliance.
