unless there is food provided for all the children then I would never accept it, like reggio I do not allow outside food, first there is the concerns for allergies and restrictions that all parents are not aware of, as well if one child has something and the rest do not it causes me more problems than not so I just do not allow it. The only exception I had was one child in care was a vegetarian so mom and I would sit down and once I had my meal plan together for the week she would send protein options if needed but normally I would provide it all.
