From Alexander Patterns:
The task of looking after little children is a much deeper and more fundamental social issue than the phrases "BabySitting" and "ChildCare" suggest. (Raising Kids)
In every Neighborhood, build a children's home- a second home for children- a large rambling house or workplace- a place where children can stay for an hour or two, or for a week. At least one of the people who run it must live on the premises; it must be clear, from the way that it is run, that it is a second family for the children- not just a place where baby-sitting is available.
