What is the reason for the slight redness and swelling of the foreskin in children?

Patient's question:

Basic Information: Male, 1 month
Disease/Symptoms: Red and Swollen Prepuce
Description of Condition: The male baby was born eight days ago. Today, it was noticed that the prepuce in front of the baby's penis is slightly red and swollen. What could be the reason?

Doctor's answer:

According to the child's current condition, if it is not caused by biting insects, it may be due to local inflammation. It is related to poor hygiene habits or phimosis. For local medication, appropriate oral antibiotics should be considered. 1: Use a 1:5000 potassium permanganate solution for external irrigation treatment. Considering the irritation from diapers or diaper rash, the penis of an eight-day-old infant is slightly red and swollen. Pay attention to feeding, do not urinate after wetting and licking the external genitalia, and use clean cotton diapers. Avoid using diapers as much as possible. Wash the external genitalia and anus with water every day.
