Yes, I understood that. But something in me was thinking that if you are sort of providing a service, even though not connected to the preschool, that someone might "come after you" for not providing the proper nutritional needs for their child. Even though many schools offer junk as food, as long as the food somehow satisfied a food group, even if it crappy, it's ok.
So even though you are going direct to parents, it would be a selling point to say that you are following the standards for schools and THEN some. This will help them to see that they are getting the right stuff and then some. KWIM?
