Best products for sick/congested baby?

My 3 year old caught a nasty cold and now my 7 month old has gotten it.

He can’t sleep the last 2 nights because he is so stuffed up. I use saline mist in his nose and suck out all the snot. I use baby vicks on his chest. I gave him a bath in a vapor bubble bath. Humidifier, too. He is so miserable. Keeps waking up covered in snot and his eyes matted shut with it.
