9 yr old has cough 3 days. sounds like seal bark no other symptoms. what can i do for cough? he is not getting rest from all the coughing.

Laryngitis/croup: Sounds like a laryngitis or croup, which is an inflammation of the vocal cords mostly from the virus and common among the young children. I usually recommend to inhale a steam from a bowl of hot water or from a warm shower. Sodium bicarbonate (sodium bicarbonate) 1 tsp could be added to the bowl. Be careful and don't get burns. Use humidifier in the bedroom. Drink a lot of warm tea (chamomile or lemon tea). Best!
