"Absolutely that's an important aspect," says Catherine Theroux, a spokesperson for LIMRA, a global financial research and consulting organization. Research by LIMRA shows that seven out of 10 households would face financial difficulty immediately or several months after a primary wage earner's death."But life insurance also has use for paying to replace some of the household services a parent provides, like child care," Theroux says. "The value (stay-at-home parents) bring to families would cost a lot of money if they weren't there. It's important that people recognize it's not just income you're replacing." Assuming grandparents will step in to pick up all the slack is unrealistic. They may not be physically or financially capable to do so. "You have to provide a cash cushion in the event a parent passes away," says Marvin Feldman, president and CEO of Life Happens, an industry-supported nonprofit that educates consumers about insurance.
