The daughter seems to have a runny nose. She often coughs, she seems to be getting better and yesterday she took her bath. She coughed frequently today. I spray aquamaris in my nose and use an aspirator. Sometimes she coughs once. ☹️. But I thought it was from the foam and mucus from her mouth... There's not much coughing. What should I do?
