I have two thoughts here. I have not read all of the replies, so I hope I don't repeat anything.
I think washing your hands well and rinsing your mouth will keep kids healthier and less cavities, so I really think that is not a bad thing.
I do not think peanuts in general should be banned. I doubt any child is so allergic that they cannot be in the same vicinity as them, I mean do they keep these children out of the grocery store? I think you can have care and at the same time not go overboard.
My daughter has a peanut/tree nut allergy. I homeschooled her until I got cancer and my husband wanted my kids in school so I would have less stress. I suppose I could homeschool her, but it would be challenging on the chemo weeks. She does get break outs some times, but we give her benadryl and encourage her not to eat stuff she knows she shouldnt.
One day I was called to come pick her up because she had a swollen face and a rash. They have her allergy information, her tray at lunch never contains nuts. Well they had an alacart item that happened to be a cup of shelled walnuts. She took it and ate the whole thing (and rubbed her eye with the hand she used to eat them), her eye was all swollen. I did not freak out. I just asked how she got walnuts, they explained what happened and I was like, ok Sarah, do not eat nuts. (She knew better, just wanted to see what they tasted like
) They decided not to have any nut items. I disagreed with that, because it is not fair for the others, Sarah needs to stop getting what she knows she shouldnt and the worker know she cant, and so she wont let her.
Now I do not think they should have food that has hidden nuts (cooked in peanut oil etc)
