Totally normal when you send to CC, PG or Pre N they will cry as it is new environment for them. Perhaps, you might want to share with the teachers, pretty sure they will be able to tackle and learn her likes/dislike. Sometimes they need assurance that it will be okay and some comfortness. Check with the teacher her progress. And I am also sure she will also have her favourite teacher sooner later. It will take awhile but slowly. Don't give up neither feel the guiltness. We need to let the little one be out of their comfortness. Jia You!!
