Let me be clear: my kid is not Mr Popular, I'm not the perfect mom, but w/almost any other family I've interacted with, I wouldn't have felt the need to post here. I would be on the phone with the parents ASAP and not think twice about that as the obvious address for ensuring that the kid's crisis was handled.
In this case I'm genuinely concerned the parents will either blow this off or shame/bully the kid (as I've seen them do over physical appearance issues.)
I am the PP from above that called the principal.
You should call the school, they deal with this all the time. You are not equipped to handle this situation. Even if the family is not off putting it is hard to receive this type of information from "some mom".
Don't worry about the other posters. Your instinct was to tell, you child was right to tell you, now tell a counselor or a principal.
