Thanks for the responses. I talked with DDs teacher and she was really supportive! She said they were having problems with a particular child and they would keep a close eye on the situation.
The class room is very play based, and the activities are open ended enough for DD to do as much or little as she wants with stuff. The peer interactions were a little more of an issue, but the teacher seems aware of it.
DD is excited to go to preschool and said she wants to go every day. I am hoping that if we keep her engaged at home and her confidence in her own skills increases things will be fine.
I also will follow up with the teacher in a couple weeks, and the teacher said she would let me know if there are problems.
DD is reading to lots of different adults and siblings now at home and seems to be gaining more confidence in herself after we talked to her about it and I went to her class.
