Preschool anxiety

My little girl is starting preschool and I am very nervous that she will be picked on. She has to wear an eye patch and already, when we go to the playground little children go to poke her eye or ask her why she has it covered. I am right there to correct those behaviors, but I won't be there at preschool.

I am so nervous. She is so confident. I don't want her to lose her spark.

We are having a courtesy meeting with the preschool teacher who will have her at her class. Besides raising my concerns, is there anything else I should ask her or tell her?
