In my house we swear by the nose frida. Also get a humidifier it will help alot. But for the time being you can go in the bathroom and steam it up and sit in there with her. That will help with the stuffy nose for right now. Unfortunately there isn't a whole lot you can do because your baby is only 4 months old.

Go in the bathroom and steam it up. And sit in there with her
