hello Nihit is 5 years old and he is coughing little bit specially during sleeping time. His nose gets stuffed sometimes but I make him flush out the watery mucus from time to time from the nose. I have started giving him steam for about 10 minutes from today. Apart from this I am giving him a glass of lukewarm water three times a day. Any cough syrup or nebulizer or medicines are needed, please let me know.
