As there is no fever
nothing to worry but frequently instil nasal saline drops in to nostrils and clean then especially before feeding. To decraes the nasal discharge you can give oral antihistamine drops after consulting your Pediatrician
in prescribed dosage. If there is thick secretions instill nasal saline drops and gently do suction with a mucus sucker to clear the nostrils.
