it is difficult to comment here because it is such a serious issue and it can be a he said/she said issue.

Your daughter would greatly benefit from a neuropsychological evaluation which looks at both medically based origins of behavior as well as should examine emotional issues such as attachment. Given the symptoms you describe, I srongly encourage an assessment by a child psychologist. - Dr. Varia
Hello! I believe Dr. Resnik responded to the same question you posed from the day before. I hope that helped. - Dr. Varia
