My 2yr4mths daughter had phelgm coughing lask wk, seen a pd taken med, everything seems to recover except for dry night cough, may i know what shd i do?

Humidifier: At 2 years of age a cool mist humidifier in the bedroom and possibly honey to help. It can take 1-2 weeks for a cough to clear after an infection.

Try saline rinse: Saline can be quiet helpful during and after a recent cold. It clears the nasal passage and adenoid area. Use distilled water and a commercially available saline packers (Neilmed sinus rinse)
