Many women who care for children while holding down a job are feeling overwhelmed by the stress of trying to balance both important responsibilities.

In a survey of 1,000 working moms by, which helps parents find and manage family care, women report working an average of 37 hours per week while spending another 80 hours on child care, household chores and other matters.

According to the survey, more than a third say they're always falling behind, while two thirds imagine that others are more together than they are.

Three out of ten working moms won't hire someone to help because they feel guilty about not being able to handle things by themselves.
