I have a family who's parents don't work for the summer, and seem to come and go as they please. It is so disruptive to our routine(late dropoffs without notice/ pickup at awkward times like sleep time etc.) Now they want to dropoff today an hour before my closing time. My contract says all kids must be in by 9am. How do I address the fact that I'm not a drop-in service? Also, what do you have in your contracts about dropoffs? Do you have a set cut-off point for not accepting them during the day? Thanks.
