BBdust,
His nose seems better cause the "guim guim" sound seems lighter but still got mucus leh. His dad very clever, don't want his son to think he's the bad guy so everytime ask me to suck mucus. Hmpf but okay lah, when I see the mucus coming out, I also very happy. Thanks for the recommendation of Sterimar, its really good! After I spray inside, sucking of mucus is almost simple as ABC though not a lot lah but at least I can see it flowing out lor.
