When I reached out to the school counselor for my S8 I did cc my H. My position if challenged (which it was not) is that it is a health issue that my H is entitled and obliged to know about. It ended up helping a lot since the materials the counselor sent home with S8 resulted in H making some adjustments to the kids' environment that mattered a lot to my boy... And I didn't have to get involved.
I would say that your H ought to know this stuff because if it escalates and you HAVE to bring him in on it later, he would be frustrated to not know about it as it developed. Rightfully, in my view.
I'm sorry your little D is struggling. It's good that she's speaking out so that you can support her.
