A young mother of a 4 year old child expresses concern regarding the milk her child is drinking. The family purchases milk with WIC (Women Infant Children) government assistance. “I am not allowed to purchase organic milk” she states. The mother goes on to explain “I heard regular cow’s milk has hormones in it and I am worried about giving it to my child.”

How would you respond to this mother? Would it be prudent for her to forgo her WIC coupons to purchase organic milk, almond milk or soy milk instead? Think about what your answer would be before proceeding with the questions.
