Oh dear.
There's a lot to be said for tiny flexible schools.
My eldest attended a school that understood that kids have meltdowns and can act a bit wild. Whenever something would happen with the little kids (e.g.
The Haunted Bathroom; don't ask), he would sent a nice email to the parents of everyone involved saying a) what had happened and b) "We know that these kinds of things happen with the young ones. Part of our job is to help them grow and mature so that they can learn to avoid these kinds of situations."
I suspect that the people at your' daughter's school know this too.
