Tell the teacher what you have observed about your daughter's learning style and that you think your daughter would feel more comfortable if the class was not rushing quite so much. Explain also that you believe your daughter may be showing signs of stress (talking in her sleep) since she began school.
Before you meet with the teacher, talk with the school counselor. Explain the situation and ask the counselor to be present at the conference to address the issue of stress in young children. The counselor can speak for the other children in the class as well while you speak for your daughter. The counselor can also address what is covered in the kindergarten curriculum and discuss what is being taught in the other kindergarten classes.
