My six year old had covid (we all did) 3 weeks ago. When he tested positive his symptoms were pretty mild, mostly an intermittent cough. In the past week the cough has got pretty bad, especially at night. It's hard to describe, not exactly chesty or dry but the coughing spells can be quite long.
I hadn't brought him to the doctor as no temp, phlegm not green/yellow and generally he's up and about living life fine. But any tips for how long to expect this to last or any home remedies to help with the cough?
