My daughter is having cough since more than 40 days. We tried many cough syrups and medicines initially when she was suffering from fever. Now fever is gone since 15-20 days but she is not getting rid of cough while breathing she sounds very cracky and even when we touch her back while she is sleeping we can feel the vibration due to cough. When she is awake she gets less cough (khaasi) but when she goes to sleep it becomes frequent and gives a big challenge to remain calm for more than 3-5 mins. Due to this she ruins her sleep at night. Please suggest a suitable cure without antibiotics or steroids.
