My 6 month old baby has been coughing for 1 month?

Good morning, ma'am,

Often, coughing is caused by sinus drainage back into the throat. Do you perform nasal hygiene with saline solution and a nasal aspirator? This is the best treatment, and can be done as often as needed during the day, and at least 30 minutes before bedtime. It's a little uncomfortable, but works wonders for reducing the runny throat that often causes coughing.

I hope this helps, and don't hesitate if you have any other questions!
