thanks for writing to health care magic.
development of cough
could be mean aspiration of the oil ingested.
but cough could also be because of a viral or bacterial infection and it could be coincidental.
monitor the respiratory rate
. if you think baby is breathing fast or there are chest retractions or development of fever
you may have to contact your doctor immediately
In such scenario the questions are directly forwarded to me .............. and I can answer your queries regarding your kid online regularly.
Hope this helps.
