The school is smart to keep this kid out of the school because the next step will be his mother demanding that peanut butter be banned lest some kid have to administer artificial respiration to him and inadvertantly kill him after eating peanuts.
It's ridiculous to pretend the kid's circumstance is normal and that all harm can be avoided IF other people simply change their behavior, get educated, and avoid eating peanut butter sandwiches.
I have entirely too many of my own allergies and health concerns to go around worrying about the folks with nut allergies anyway. My focus is on banning wheat, barley and rye, and strictly limiting the preparation of white kidney bean extracts ~ and hold the peach skin fuzz while you're at it.
Nut allergies(including peanuts) used to be rare — or so it seemed. But my husband has severe tree nut and peanut allergies and he is now 80. At the time he thought he was a wierdo having them. He went thru the school system and was able to take care of himself by using his head. No one had to change their behavior. No Epi-Pen then.
And my daughter, now 49, has both peanut and tree nut allergies, —— and fish and shellfish allergies. She too learned real early in life what she should do to avoid a problem. I’m sure the school was full of PB sandwiches and brownies, but she was the one who adjusted. No Epi-Pen there either.
