So many families have no choice but to be dual-income. With the cost of living rising faster than wages and divorce rates elevated, many parents are unable to volunteer in their kids' classes. Some parents have to put their kids into after-school care with people they don't know all that well. Homeschool parents also get overwhelmed, particularly if they have children with developmental, physical or behavioral disorders. Grandparents, retired from full-time work, can play a valuable role in the lives of their grandchildren while providing some much needed help for their children.
