This paper explores some of the attributed of quality day care programs for infants, age 0 to 30 months. High-quality interactions with adults result in positive developmental outcomes for infants. Adults involved in day care should focus on providing an environment of stimulating experiences, which help infants to develop satisfactorily. Other critical factors in adult behavior are values and attitudes, particulary interpretations of good and bad behavior, methods of discipline, use of materials, and the degree to which daily housekeeping chores interfere with constructive adult-infant interaction. Tips for teaching infants are provided along with an outline of appropriate developmental tasks for infancy. Important aspects of physical layouts for centers concern safety precautions and the division of the facility into interest areas. Daily schedules are discussed; strong organization and planning are stressed. Continuity of care is vital and may be facilitated by having few caregivers for each child, encouraging caregiver-parent communication, and maintaining a low level of staff turnover. (DP)
