hi nat, about 6 months ago i put my boys in a nursery one day a week while i was at college and i had more or less the same problem.they were there every wednesday from 9 till 3. the first 2 weeks were fine, the boys seemed to be happy there. but on the 3rd week i was called out of college as the oldest was upset and they said they couldnt stop him crying, the 4 th week they were in there half hour when i was called out as they were upset again. when i collected them they were both sat in pushchairs which i want happy about. i asked the staff remembering there were4 staff members and only about 10 children, why they were in pushchairs and she said cause they just wanted to sit on my lap and wouldnt play. my argument was why couldnt one of the staff members sit at the table with them and play with themand try to reassure them a bit. she told me i had a point and they would try it next week. i took them in and again after 2 hours i had the call i was waiting for, only this time when i went to get them the older one was sobbing in his pushchair. when we got to the car i asked him to calm down and tell me what was wrong, he replied the lady scared me, i asked why and he said cause the lady smaked ryan ( his brother ).
i am not sayin it is the same for you but maybe there is a reason why she dont want to be there, or maybe she just misses you and they dont have the patience with her. it is so easy to blame the nursery when sometimes it is just that the child misses mommy/daddy. maybe you can ask questions, find out why she dont like it.or take her in but secretly watch from outside, see what she does when you leave.
