Using day-care seems inevitable and and mandatory for many. This research indicates that quality matters, but maybe more important is the duration of care outside the home and the intimacy of family relationships when the child returns to parent’s care.
“Researchers had speculated that the negative effects of lower-quality care would disappear as the influence of other factors, such as peers, teachers and maturation, overcame the early childhood experience. But in the latest analysis of the data, they discovered that teenagers who had received higher-quality child care were less likely to report engaging in problem behaviors such as arguing, being mean to others and getting into fights. Those who spent more hours in child care of any kind were more likely to engage in impulsive and risky behaviors.”
