At first I misunderstood and thought the guideline was about what a parent could send for their own child but I see it's for sharing. So, I think it's a good policy. I do have issues with people telling me what I personally HAVE to give my own child, beyond the obvious allergy issues which I am happy to comply with.
Truth be told, we do shop and eat that way anyways. It's just something about rules that get my back up!
Probably off topic but coming back to the "no homemade" stuff, that kind of thing really bothers me. I feel like we are raising a generation of food phobic kids who don't see homemade food being prepared, not anyone specific on here just in general and probably mostly mainstream. So many people don't have time or care to prepare real food from real ingredients and sit down and enjoy it together. There is little reverance for food these days which I find sad.
