Not sure if this has been brought up before, but I want to know if anyone has anything about this in their handbook/contract.

Here's a question my husband brought up to me as I was reviewing my handbook with him. I was going over my injuries/emergency section with him and mentioned that if a child had to go to the hospital by ambulance, it was the parent's resposibility to meet the child there, as I had to care for the other children.
So, the question my husband brought up was, "if you have to call an ambulance, who pays for it...you or the parents?"
I had never thought of this, and I'm not sure who should pay for it.... what do you guys think? Do you have anything in your handbook? I'm really not planning on ever having to do this, but would like to have a plan in place.

TIA.
