An Ohio day care center has just been sued by parents of children who were allegedly given the supplement Melatonin to make them sleep during the day. The lawsuit accuses the day care center of negligence, battery and negligent supervision for injury to the children who were given the supplement. The suit reports the children suffered injuries that required medical attention, sustaining medical and hospital bills. Parents should be on watch for irregularities in day cares, and it is advised to perform surprise inspections during the day.
