General Measures:

  • Use a cool-mist, ultrasonic humidifier to increase air moisture. Clean humidifier every day.
  • For a baby too young to blow his nose, use an infant nasal aspirator. If mucus is thick and sticky, loosen it by putting 2 or 3 drops of salt solution into each nostril.
  • Don’t insert cotton swabs into a child’s nostrils. Instead, catch the discharge outside the nostril on a tissue or swab, roll it around and pull the discharge out of the nose.
