1. Parents can clean their children's nose with a nasal aspirator and a small cotton swab when they find that their children feel uncomfortable because of excessive nasal mucus or scab.

2. When a child has a cold, nasal drops can be used under the guidance of a doctor to eliminate the discomfort of nasal congestion.

When the weather is dry in winter, give children more water, eat more vegetables and fruits, and put a humidifier in the room to make the air more humid.

If you can make your child's little nose feel comfortable, you can naturally avoid the bad habit of picking your nose.
