With Ds we wrote "Dairy" because I figured that if someone was reading a medical alert tag it was most likely because something has happened and it might be a medical proff. (emt,nurse,ER doc) as I always told the person if I left him with someone NOT feed anything like milk,yogurt,cheese blah blah and since I always packed his snacks/food I pretty much reiterated NOT to feed him anything but what I brought.
