As a parent if a child with ADD and being on the spectrum I appreciate your being so concerned and involved. However I have to tell you that the bullying is the schools job to handle, and your daughter should push them. Of course you want to help and it's upsetting, but there isn't anything you can do so I would try hard not to get stressed about it.

My H is in the picture now but wasn't during the worst times concerning my daughters behavior and school issues. I managed on my own by getting the school involved and getting her meds right. Therapy helped only when they served as advisors for me- she refused to go and when she did go, refused to speak. So it might not worn for your grandchild right now unless your daughter needs a T to help out with the school. kids on the spectrum don't always respond to talk therapy.

You are very kind but try to take care of yourself first and encourage your daughter to get on top of school admin to take care of the bullying issue. They have to so if they give we trouble an advocate or lawyer is what she really needs.
