My 11 week old son is stuffed up on a fairly permanent basis without really having other symptoms. This seems to affect his feeding (I imagine he can't breathe well while feeding) and his sleeping (I think he may be panicking because he can't breathe very well). We use saline spray but this only helps in the short-term. I was wondering if there is a humidifier or vaporiser which is OK to use for a baby of his age. Can anyone recommend anything?
