NYTimes.com | Poor Behavior Is Linked to Time in Day Care

A longitudinal study on child-care in America, conducted by the National Institutes of Health, finds that a year or more spent in a child-care centre appeared to slightly increase a child's chances of being disruptive in school later on. Interestingly, the apparent effect of child-care attendance was matched, if not slightly surpassed, by the effects attributed to parents' own dispositions and the ways in which they reared their children.
