Dear Laura,
My 12 yr old child had several times last year when she would react to gluten from something at school. I think the main reason was that they sit so close together at lunch. Other children's food particles seemed to "fly" through the air alot! The smaller the child, the worse it was. Several kids have dropped their pizza crust in my child's dish accidentally. Also, their little gluten hands touch everything! The soap in the dispenser in the bathroom also contained gluten. It seems sad to separate them from the group at lunch, but that's what I've done and it has helped tremendously.

Hope this helps.
Beth
