Fortunately, she's a very charming kid. Even the teachers who struggle with her still seem to like her and she makes friends with other kids very easily.

I have no problem with teachers setting expectations for their classroom and trying to maintain them. If she's too disruptive, they can ask us to take her out (which her dance teacher has done before).

In my opinion, the important lesson she needs to learn is not the specific rules of each classroom, but rather the importance of cooperating with people who have something valuable to offer you.
