I agree that she is asking for something you do not OFFER and you are under no obligation to offer ~ I have a no outside food or drink unless there is a MEDICAL requirement that I cannot accommodated ~ so no would not allow her to send food from home based on a 'lifestyle choice' you eat what is served here that is my policy and if she is not ok or comfortable with that than this is not the program for her and YES I would encourage her to find alternate program that is more in line with her 'lifestyle' and parenting views around nutrition!

I am not sure about your neck of the woods but in my city there are lots of providers who are taking this focus in their programs ~ they charge more as a result because organic eating is costly ~ however if she truly wants to have these options for her child she should be willing to invest in them!
