When drop-off at daycare goes from bad to worse -- a screaming, crying child who has to be peeled out of your arms -- you can't help but wonder: Is there something awful happening at this place? Have I made a terrible mistake? Assuming you've done a good job of choosing and vetting the day care, the answer is most likely, No.
