Have you tried rubbing Vicks on his chest and feet and then putting socks on? Also propping up one end of his mattress? I was skeptical that either of those things would actually work but they've been helpful for us. Also some people say to give the baby honey...haven't tried that one myself.
Maybe zarbees I always do steam humidifier if its more than 3 days you should be seen dr sometimes put kids on nebulizer depending on frequency and other items.
