I concur with skylersmommy about talking with the teacher. I would specifically ask her if anything's happened to make your DD feel like it's not OK to read in the class. If it turns out your teacher is somehow behind this, then you'll want to run away fast. I think the early teachers do have a lot of influence on our little ones, as in "if mrs. so and so said it, it's true!" Maybe you could ask the teacher if there could be some times when she asks your DD to read something, either to her or to the class.
