good evening, as per the symptoms history and family history , ur child might be having hyperactive air ways. nebulisation will do no harm to the child nor the child will get addicted to it as u have thought. u have to avoid dust smoke strong odors , cold
enviornment , plant pollen, chalk dust etc which r triggering factors for the cough
. vent pd will help in this situation but not permanently. she might get cough again, just watch for the severity involved in the cough- fast breathing chest retractions audible wheezing
soud ect, she ll need an emergency care in these situations. kindly review wid ur doc for a detailed evaluation and rule out asthma
, thank you.
