So the parents drop off their kids at Airsoft Day Care, and leave?
You guys are in for a liability NIGHTMARE. If one of those kids gets hurt, even a pricked finger. You could be held responsible and liable for all injuries to that young person.
Essentially by allowing these children to be dropped off, regardless of what waiver has been signed. You are assuming responsibility over those young persons.
My advice would be to stop that practice straight away. If the parents are not on the field, then the child cannot play.
You may have been running on luck and borrowed time for now. But the day will come, when something happens.
