My baby has developed a dry cough? - baby has dry cough

My 4 months has a cough and not today. A dry cough. Say, no other symptoms of cold can. Should I go to the doctor, or simply stand and wait to see if they are nothing. She has an appointment to see a doctor for your next Friday, 4 months plans. (I'm from a cold to me w / sore throat) Do you have any idea how I can prevent it from worse for them?
