When Ian was five, his food sensitivites were pretty bad. He only ate certain foods. His gag reflex was so sensitive that I had to mop up vomit off the kitchen table a couple times a week. Lunchtime was particularly difficult, because he would only eat peanut butter sandwiches. However, I wasn't allowed to pack any nut products, even Nutella, for school lunch. There were too many kids in the cafeteria with severe peanut allergies.
I can't remember how we resolved this problem though I do remember lots of phone calls with the school. I think he ate his lunch by himself in the hallway for a few months, until I figured out another food that he could tolerate.
This was my only issue with the Peanut Police. In fact, I am very sympathetic to their needs, because my BFF has a daughter with extreme celiac disease. I know what one stray gluten can do her. My BFF has to educate teachers and other parents, because people are constantly handing her kid questionable snacks and treats. She has to pack alternative foods, whenever her daughter goes to a birthday party. She had to track ingredients in everything from medicine to condiments. It's a lot of work, which is very similar to the work that I've had to do with Ian.
So, I am very sympathetic to the article in Slate about a parent who pleads with other parents not to bring snacks to the playground and to clean their kids' hands with wipes. But the commenters on the peice were not so sympathetic.
