Stephen Baskerville states that shared parenting has been demonstrated to reduce parental conflict by requiring parents to cooperate and compromise, and that it is the lack of constraint by one parent resulting from the ability of that parent to exclude the other, that results in increased parental conflict. He further states that only when child support guidelines exceed true costs do parents ask for or seek to prevent changes in parenting time for financial reasons, adding that any argument that a parent is asking for increased parenting time to reduce child support is at the same time an argument that the other parent is making a profit from child support.
