It makes a difference too whether they are gluten free by choice or by medical need as in any cross contamination - both kinds of crackers on the counter at the same time would be enough to give the gluten sensitive child a reaction so it is more than just mom sending the food.

For sure she provides it all for the day as someone mentioned to hard to read labels all day or to know exactly what fillers are also a no no. I would also not be lowering my fee any either in that while I am not providing food I am having to spend extra time being conscious of who is eating what, it will limit things like baking experiences for the group or cause me to spend extra to buy special products so that when we bake all can touch the ingredients and eat the final product.
