The circumstances that make full time caregiving of children necessary usually are not ones grandparents or relatives would happily choose. Such situations arise when a child’s parents become unable to continue in that role because of substance abuse, mental or physical illness, long-term unemployment, incarceration, military deployment, or death. Relatives step in as caregivers because they know their home is a more stable, loving environment for the child’s well-being over the long term than placement in foster care.
