Oh, yeah, in preschool, they would approach me and ask if certan things were safe *for other allergic chidren.* When I said something to the director, that I could not be certain what was ok for other kids, not knowing how they do things and all of their allergens, she would give me a look and say, "Oh, well, you are more careful that his parent, and I do not want to hurt this child!" She was not naming the children in these cases. But very, very many people are much less careful than out small group here. I dare say, most. In my community, anyway.
One of the kids in the class was recently at ds's bday. No epis. He ate the pizza and cake. I made the cake and it was safe for dd and I had vetted the pizza for her too. I did share my info with the dad, and we even discussed the allergies. Got the, "his aren't so bad," line.
