I would suggest that you follow your doctor's advise . Please give your child medication as advised by his paediatrician. Also, the doctor has ruled out the possibility of a chest infection
, so don't worry.
However, I know it is difficult and heart breaking to watch your child in distress. One possibilty is post nasal drip
which causes the cold
& secretions to trickle down the throat ,thereby causing cough
. You could try applying a little vicks
on his chest. Make the baby lie on his left or right side. You could try giving the baby a little honey mixed with a pinch of pepper powder. All these measures might help reduce the cough.
You might also want to try steam inhalation along with your child. Please be careful.
Hope this helps.
