This monograph tells of an era when an increasing numbers of working mothers found day care down the street with a mother who had a child or two of her own and was glad to add one or two more during the day. Informal family day care met with respect by a team of researchers in Portland, Oregon. They studied family day care and discovered ways to create “natural helping networks” in the neighborhood.
