Newborn diaper rash

Patient's question:

In the past five days, I have noticed diaper rash on my buttocks
There are no signs of rupture, oozing, or infection!

Doctor's answer:

The cause of diaper rash is the skin coming into contact with urine in a damp and warm environment. Therefore, choosing diapers with strong absorbency and good breathability can keep the area dry and prevent overheating, eliminating the conditions for the rash to develop and naturally reducing its occurrence. Developing good hygiene habits is essential; parents should change the baby's diaper promptly to prevent them from wearing a wet and damp diaper for too long. Before changing the diaper, parents should wash their hands thoroughly with water and soap to avoid contaminating the diaper with bacteria or transferring it to the baby.
Before putting on a clean diaper, especially after the baby has had a bowel movement, it is necessary to clean the buttocks with neutral soap and warm water, then gently wipe them dry with a soft cotton gauze. Ensure the skin remains dry and apply a moisturizer to keep the skin hydrated while reducing the opportunity for contact with urine. The baby's buttocks should be exposed to air and sunlight for a certain amount of time each day to allow the skin to breathe freely.
If diaper rash does occur, keep the affected area dry. Expose the buttocks to sunlight appropriately, but avoid rubbing the rash. After cleaning, dry the area thoroughly with a soft cotton gauze. Apply petroleum jelly or an anti-inflammatory ointment locally to create a protective barrier that isolates the skin from irritants. In severe cases, seek medical treatment promptly.
