I would ask the pre-school what strategies they are using to help your daughter. If this is happening in pre-school only, it is really a problem for them to solve and not your responsibility. I am sure that the situation with so many children there maybe not helping your daughter who is used to being an only child.... however, she will not be the only child to behave this way. She needs the pre-school supervisors to manage her behaviour as you aren't there at the time... and she doesn't behave this way with you.
Sure, ask them how you can support them , but they need to initiate some strategies to enable your daughter to learn to cope better in the pre-school environment.
Good luck....
