WASHINGTON, DC

Washington, DC law does not provide age-specific child supervision guidelines; parents are expected to use their own good judgment. However, they do provide some insight into when leaving a child alone can cross the line into neglect.

In general, infants and young children should not be left unsupervised for any period of time. For older children, how long they may be left unsupervised depends on their individual maturity level, and they note that there is a difference between leaving a child or teen at home unsupervised for a couple of hours during the day versus all day, overnight, or for several days. The less time children are left unsupervised, the lower the risk (Source).
