Don't fret if things didn't go as well as you'd like at drop-off; it's totally normal for things to be a bit bumpy at first. Worried your child hasn't calmed down? Ease your mind by giving the preschool a call, but try to wait at least 30 minutes before reaching for the phone. This allows just enough time for your child and teacher to get adjusted.
