Step-by-step explanation:
The term for child care that occurs in the home of a nonrelative who usually cares for several children of various ages is known as non-relative foster care. These foster parents are state-certified and provide care under the guidance and supervision of relevant agencies. They must comply with various guidelines and often receive financial support to aid in the care of the children entrusted to them. This arrangement can be part of a wider extended family structure which also includes various other forms of out-of-home care. Within the United States, there has been an increase in different family dynamics, resulting in various custodial arrangements including extended family households with relatives such as grandparents, adult children, or aunts and uncles all living together.
