I thought of this thread the other day.
We are deep into the grey area of FA, having passed an IOFC yet still having symptoms (itchy tongue, hives, swollen eye - allergist thinks probably just contact rxn, I'm watching like a hawk).
We met with the school nurse and she had prepared an allergy bracelet for dd (stating her specific allergy) to wear at school. This school has some excellent policies in place, and I didn't sense that they wanted anything but to keep the children safe, yet they were totally unaware that there was a problem with this policy. I mentioned FERPA and how this could also present a danger to the child having this info widely known ... she seemed to agree. I will probably gently give her a few printouts in a few days when I see her again. It's not an issue for us personally at the moment since dd won't be wearing it.
