Two week old congested-

My babe is congested... nothing more so I’m waiting to call his doctor unless he shows more symptoms of a cold. We have a Vick’s hot steam humidifier that I’ve been having on all day. Is it ok to use the Vick’s liquid and everything with him in the room? I just had a vapor pad and that’s it so far. I’m trying to do research on cold steam vs hot. What else could I use to help him? He’s not having any breathing troubles. Just a little stuffy.. Any help or tips would be greatly appreciated!
