my 17 months old son is with runny right nostril for more than month. Last winter he was with runny nose until summer. He is mouth breather from more than 1 year. Im worried so much, because he cant sleep well, cant eat well and is tired all the time.
Your child may be having an allergy problem (atomic), which requires regular treatment. Please consult your Pediatrician. His adenoids may also be big and obstructing his throat, for which he is a moth breather and not sleeping well.
