Hello doctor, my daughter us 5.5 yrs old..17 kg..from the last 1.5 months she is having cold and cough. Now cold is not there but cough continues..doctors have suggested Relent and Ascoril initially. But she didnr recover complety. Then changed to Alerid and Ambrolite. Even with all these her cough persists. I have observed that kids in neighnorhood also have cough this winter. Is there anything else you could suggest to help her recover
