They should be helping you to help her settle in, if the best they can manage in front of you is telling you to take her away then imagine what there care levels are like when your not there to see it? If she were mine I'd be looking for a new nursery.

Sounds like she's not really ready for nursery, I understand that sometimes you have no choice but to work but if you do have it, I'd stay at home with her until she's a bit older.
