Our baby suddenly started bleeding from the nose, possibly due to a cold or nasal congestion. Immediately apply pressure to the nostrils with the thumb and middle finger to stop the bleeding. If it continues, repeat the pressure for five to ten minutes, and most cases can be treated with medication. If it’s still not effective, seek medical attention promptly. During treatment, the patient should pay attention to their diet, maintain regular work and rest , actively participate in physical exercise, maintain physical and mental health, and avoid bacterial infections.
