Another way longer paternity leaves help new parents

A longer paternity leave can improve the co-parenting relationship between moms and dads by making mothers less likely to discourage fathers' involvement. When fathers take more time off after their child is born, mothers relax unrealistic high standards for fathers' parenting and are less reliant on others' evaluations.
