Self Harm

Any help or suggestions would be greatly appreciated!

I have a first grade little girl that is hurting herself almost daily and it is escalating in severity. It started at the end of last school year with minor things, like picking her nose till it bled and picking at an insect bite or scab till it bled, etc. Now she is putting stuff in her ears, biting her tongue till it bleeds, cut her ear lobe with scissors, gaging herself till she vomits, and so on. There is an injury involving blood daily. The teacher, myself and counselor have all talked with her and tried to give her other ways of coping and dealing with stress. I was just informed that yesterday, during a meeting the teacher had with the mom (I was not invited to this meeting), she told the teacher that before the little girl started school she had pulled out her toe nails several times and has pulled out 14 teeth before they were ready to come out. I think the mom is in denial that there is a problem that needs to be addressed. She needs constant supervision but of course in a large class room and one teacher that is hard. I am so scared and worried for this child! Admin is aware of this child and what she is doing but, still noting is getting done! I want to get her help but don't know where to turn.

Has anyone dealt with something like this before? Any suggestions would be great!!
