Discussed in this ERIC Digest are the quality of infant day care and aspects of the debate on infant attachment. Characteristics of current infant day care provisions are reported. Program quality is discussed in terms of: (1) structural features, such as group size, staff-child ratios, caregiver training, equipment, space; (2) dynamic aspects, including experiences and interactions; and (3) contextual features, notably staff stability and turnover, and type of setting. A section on effects of infant care points out that while several studies show that day care may benefit low-income children and have benign, if not beneficial, effects on middle-class children, research findings on socioemotional development are not unanimous. The concluding section discusses attachment in terms of the controversy about day care for infants under 1 year of age and studies comparing home versus employed mothers. (RH)
