Hi I moved from tamilnadu to Bangalore yesterday. My baby is 21 days old when he breathe I can hear some gur gur noise like mucus is blocking his way to breathe. How do I know it is cold or due to excess heat?? Also his eyes are forming watery and mucus forming

A. Cold is most of the time because of viral illness and if the child is having recurrent running nose and nasal congestion it may be a part of allergic rhinitis also so it needs a proper examination. steam inhalation will be beneficial in both the cases along fwith decongestant medicine like alex cold/ hatric 3/ sinarest. As a part of viral illness there could be associated symptoms like chgough and fever which needs treatment accordingly along with a proper hydration needs to be maintained .
