Whats the best way to fight a runny nose in a 18 month old?

When Austin has a cold we always use saline drops. When he was younger we would suction out the snot, but now he will actually attempt to blow his nose or will sneeze to get it out. Also, we got a cool mist humidifier and run it in his room at night and it has helped significantly! Try those and hopefully she will feel better soon!!
