Raising children in the today's economy is a difficult job, but for the many grandparents who have been tasked with the responsibility of caring for their grandkids, they face an even tougher challenge.

According to data from the 2010 U.S. Census and the Current Population Survey, about 7 million children lived with a grandparent in either a parent-maintained or a grandparent-maintained household.

Several organizations in the metro-Atlanta area are answering grandparents' calls for help.

For example, the Potter's House, a Christian family and children's treatment center in Stone Mountain, offers a variety of services and resources for families who are in crisis.

"We are here to provide services for the individual child and the family, as well. We refer them to (the Division of Family and Children Services) for food stamps; to ministries where they can get food or clothing; we help them with (insurance) like Medicaid. We help them with the process because many times they are not aware that they can get insurance based on some dynamics," said Annie McFadden, an associate therapist with the Potter's House.

Here are other organizations that provide help to families in need.
