My boy is 7 months old. He is down with flu with a lot of mucus in his nose. No idea how to make him blow his nose. He seems uncomfortable breathing with the mucus in the nose. Any idea how to agitate the mucus out from him.

You might wanna use something like this to suck out the mucus. This can be bought in some NTUC or kiddy palace or baby shops. At this age, they definitely dont know how to blow it out. If it gets really bad, you can go to the pd and they can suck it out for you. They use a machine to do it.
