1 year old, runny nose ... FTM

Hi All,

My LO has a runny nose, today is day 5. I keep clearing it out with the salt water mist and suction but its not seeming to get better or clear .. he shows no other symptoms (no fever, no coughing, eating and drinking well and also still full of energy and hes usual self) he has been sneezing .. do I need to take him to the doctor or ride this out? FTM here so not sure how long this will last, if he has a cold or whats wrong :( the mucus is clear.

Any knowledgeable advice welcome.....

Thank you
