child care, including 44 percent of infants under 1 year, 53 percent of 1-year-olds, and 57 percent of 2-year-olds (see Figure 11-1).
This is a dramatic change from the recent past. With it have come both growing acceptance of child care as supplementing rather than competing with parental care and persistent worries about the effects of child care on children's development. The dilemmas that today's parents are facing are not new, however. Decisions about the care and supervision of young children are among the oldest problems faced by human society (Lamb, 1999; Rossi, 1977). Over the history of family life and across cultures, mothers have had multiple duties that have necessitated sharing the handson care of their infants and toddlers with others, primarily other women relatives and older children (Lancaster and Lancaster, 1987; LeVine et al., 1994; Weisner and Gallimore, 1977).
