Hi all! My 3-year-old goes through periods where her nose runs all the time. It is clear and there aren't any other symptoms. I assume some kinds of allergies. She doesn't drink cow's milk. I give her Sambucol regularly as an immune booster. Her doctor recommended claritin but I want to make sure I have exhausted all the natural remedies first. I don't have a clue though what I should be doing! Ideas?
