I've had many parents walk in and say "Sally didn't finish her snack yet." I just remind that children can't walk around with food, and I say that I'll save it and i put it in the backpack.
Sometimes the parents seem to be wanting me to allow their child to sit at the meal table and eat right then. I just say that snack time will be really soon, or I say that we'll have an early snack time. It has been a fairly peaceful solution.
The real story is that often the kids are in charge at home and the parents don't want to have the battles that would be required to be in charge of the food situation.
But I'm not scared to do it...
Dropping off a sick child has a $20 fee attaches, plus I call fr pick up. If they aren't here withing 45 minutes it's $20 per hour or part of an hour. It's also $20 for a body fluid incident.
I would term a parent who kept bringing sick children. It's a liability issue.
