nebulisation is given only if the child is having wheezing
problems. Whenever there is cold the cough will be present because of the drainage
of the secretions post nasally which will induce cough. Please do consult a good ENT specialist
as well and get a thorough check up done to rule out any nasal pathology. Till then you can safely use saline nasal drops 1 drop 3 -4 times/day to reduce the cold.
