Methods and steps: ① Wash the baby's slightly reddish buttocks with warm water every day, and dry them in the morning and afternoon for 8- 10 minutes respectively.
② After washing and drying, apply a thin layer of baby powder to keep small strands dry.
③ Diapers should be disinfected, cleaned, aired and replaced frequently. Diapers should be made of pure cotton and light cotton cloth. Never use an airtight diaper.
④ If the buttocks are red and swollen seriously, 5% tannic acid ointment can be applied locally.
