From the Document: "Children who do not live with their parents, but whose grandparents, other relatives, or close family friends provide them with a home are said to be in 'kinship care.' [...] There are multiple reasons that children's parents may be unwilling or unable to offer care or support, including military service, mental health issues, substance use disorder, or incarceration. [...] Children in kinship care are generally eligible for a Temporary Assistance for Needy Families (TANF) child-only benefit, provided they are living with a grandparent or other relative."
