When we had an IEP meeting for DS5.10 last year to discuss his progress and accommodations for Kindergarten, the SCHOOL NURSE questioned the need to carry epipen on him at all times (our request) given the fact that we had never actually had to use the epi. I made it very clear to her that it wasn't because his allergy wasn't severe but because of how well we've managed his allergies! (The one time epi would had come in handy was when he first reacted and we did not have epi on hand yet). But seeing how clueless a HEALTH PROFESSIONAL was, I realized this was a battle we could never win.
Long story short, I created a very strong emergency health care plan, stronger than any other parent at school, but we still only managed one semester of Kinder and then pulled him out to homeschool. There had been too many times when things could had gone wrong and I didn't want to take any more risks. Life is so much easier now that we don't have to think about school vs. allergies!
