my daughter is 22 months old and she is suffering from vomitting ,loose motions and fever from last 3 days but now after getting the prescribed medicine of doctor she has no fever ,no motion and no vomit after 3 days my problem is she has not taken milk or any food from last 3 days I thought it is because of fever and motions but today she has nothing and she is not eating anything or drinking the milk . what could be the reason ? is it something else or a viral infection ?
