Hello, my 2 year old son is having severe cough while sleeping since past 2 days. He was having cold and light cough since 2 weeks which I treated at home with steam and honey for cough. But from past 2 dats it became more and now even the cough is like every 30 mins or less than that. Doctor suggested to give nebulization with duolin and xyzal syrup. But I am not finding any much relief from them. He is not able to sleep in the night because of the cough. Please suggest.
