based from experience, baby is fussy kapag may sipon.
you can try to use salinase drops then aspirate out the mucus.
kapag matutulog or nakahiga, slightly elevate si baby to help makahinga ng maayos.
i use tinybuds stuffy nose oil. if you are going to try, kindly follow their chart for a 2-month old baby.
kindly consult pedia.
