Childhood Illnesses: Infant, Saline Drops

Stuffy Nose - 15 Week Old Infant

Hi Moms, My 15 week old son has a persistant stuffy nose without any other symptoms. I have treated him with saline drops, ran a humidifier at in his room and have recently started using Vicks Baby Rub first thing in the morning and last thing before I put him to bed. Any other suggestions for soothing his poor little nose? Thanks!
