Nov. 19, 2018-Children of divorce with the best long-term relationships with both parents are those who had equal parenting time.

The effects of divorce on children are largely due to how much the divorce threatens their emotional security. Several lines of research suggest that reduced parenting time with fathers threatens emotional security by preventing children from having sufficient daily interactions to reassure them that they matter to their fathers. The correlational findings of many studies show that more parenting time with fathers up to and including equal parenting time is associated with improved emotional security in the father-child relationship. None of these studies found that mother-child relationship security decreased with increasing parenting time with fathers. This means that the children of divorce with the best long-term relationships with both parents are those who had equal parenting time.
