There was a daycare recently in Oklahoma where the workers were drugging kids with Benadryl in order to get them to sleep.  I know from the personal experience that many of these daycares (some in Fishers, IN specifically) pay their workers VERY little and offer them little to no support from management.  So these fairly inexperienced workers are left with 20 screaming kids to deal with all day.  I would definitely advise that you spend as much time as possible with the workers that will actually be supervising your children and ask them as many questions as possible until you feel comfortable.
