Need help ! (Stuffy nose)

Erica • EB💋
My baby boy had a stuffy nose since he was born. He is 3months now and finally he has a running nose I say that cause the boogies are soft and flowing. I used eucalyptus  oil while he was sleep and it all came out. I just want him to be able to breath at night and not worry. I use humidifier also all night long. I just hope this pass. Any other remedies or just ideAs to help?
