My 9 week old son has a bad cough, no temperature, feeds well, dribbling quite a lot?

Cough: Any cough in this age should be worrisome. If child acting well with no fever and good intake, does not show signs of distress , you could still watch for a day or two. If cough persists , or above signs devolop , i would have the infant checked out. Hope fully he got his one set of vaccination at 8 wks .

Viral illness: If child has cough and runny or blocked nose that would be viral infection . It can be managed by saline nose drops and paracetamol. If child develops high fever, gets lethargic , not wetting nappies , not accepting feeds, has rashes or is inconsolable or not improving or as parents you are worried then please consult a doctor.
