Thank you for your query,
As your child is having cold
, oral antihistamine for cold and mucolytic
drops are required for cough.
Nebulization is required when there is associated broncho spam and your Pediatrician
will tell you the neccessity of it depending on the examination of chest.
Infants can not spit the sputum so they may swallow or vomit so nothing to worry.
Consult your Pediatrician for examination of your child and to prescribe the appropriate medication.
Hope i have answered your query.
