I serve the same thing, cheese and crackers, fruit, toast, apple sauce, cereal, my own garden veggies with some dip, hummus and pita bread, homemade tortillas chips with some salsa (sometimes fruit salsa), banana bread, muffins, oatmeal cookies and sometimes we make our own rice crispies or bread or anything I have planned as a culinairy activity. That's usually reserve on a special Friday. I see nothing wrong with what you are serving. I would simply tell the parent that she is allowed to provide anything she feels her child may need if she is not ok with the menu or do not think it will suffice. Provided she checks with me to ensure there are no allergie concerns in the daycare.
