Robert Frank, a professor of child development at Oakton Community College in Illinois, conducted a study comparing households with a stay-at-home dad and households with a stay-at-home mom. His study concluded that women were still able to form a strong bond with their children despite working full-time outside the home. Also, women working full-time were often more engaged with their children on a day-to-day basis than their male counterparts. His study concluded that in a family with a stay-at-home dad arrangement, the maternal and paternal influences are equally strong. This contrasts with the more traditional family structure where the father works outside the home and the mother stays home with the children. In this type of arrangement, the mother's influence is extremely strong, whereas the father's is relatively small. The study found that both parents play an equal role in a child's development, but the stay-at-home dad arrangement is the most beneficial for the child.
