As compared to a woman last week that thought a school should be peanut free because her young son with an allergy had a sister who went there, I think YOU are being realistic and appropriate. Good for you!
My youngest has Celiac disease. We are not a gluten free house. I prepare her breakfast first before my other child's, and the same for lunch. I wash my hands, the table, and counters meticulously. She has her own plates and cups.
We are all gluten free for supper, just because it's more simple.
