Nearly 11 million children under age 5 are in some type of child care setting every week. On average, the children of working mothers spend 36 hours a week in such care. About one-third of these children are in multiple child care arrangements. Parents have a hard time finding child care, a harder time affording it, and too often it is of dubious quality.
