The skin of infants is extremely delicate, so if they are immersed in urine for a long time or if they are wet due to impermeable diapers, red rashes or rough skin will appear on their buttocks, which is called “diaper rash” or “red buttocks”. Newborns often become irritable, cry, sleepy and refuse to breastfeed because of red buttocks, causing unnecessary mental and economic burdens to parents; in case of severe diaper rash, bacteria can easily multiply and cause local infection due to broken skin. So how to prevent and care for it? Preventive measures 1. wash often to the newborn bath, in the hot season should also increase the number of baths. Wash promptly after each urination and defecation, and be sure to pay attention to wipe dry. It is best to leave the buttocks bare for a few minutes at each diaper change. Keeping it dry and clean is the best way to go. 2. Use the right type of disposable diapers and change them often. 3. 3. Clean and disinfect cotton diapers thoroughly Always wash the diapers used by children with water. Use a mild detergent, do not use strong alkaline soap or washing powder. You can add some vinegar when cleaning diapers to reduce the retention of alkaline substances, then rinse them well and dry them naturally in the sun after cleaning. 4. Parents should wash their hands with water and soap before changing diapers for newborns. Care measures 1. If the baby is allergic to diapers, stop using them immediately and use cotton diapers instead. 2. 2. Dry the buttocks after washing, expose them to air and sunlight as much as possible in summer or when the room temperature is high to keep them dry. 3. 3. apply diaper rash creams, such as de-wetting oil, heated and disinfected vegetable oil, and 10% tannic acid ointment, to the area where diaper rash occurs. 4. Treat newborns early if diarrhea occurs.
