What can you do for a 2nd grader who's loved school since she was three but now cries every morning all day at school and says the teacher is mean?

What can you do for a 2nd grader who's loved school since she was three but now cries every morning all day at school and says the teacher is mean?
Does your daughter tell you in what way is her teacher mean to her?
Does the teacher pick on her?
Does she say mean things to her?
Does she physically hurt her? You need to ask your daughter these questions. If your daughter is crying in the morning, not wanting to go to school and it is because of her teacher, then you need to go talk to the teacher and the principle as well. Always believe what your daughter is telling you until proven otherwise, because if your daughter is being abused at school, I would hate for you to trust whatever the teacher is telling you over your own daughter's claims.

Just try to be sensible about it.
