1, do not wear open pants for little girls, wear loose fitting clothes and pants, skirts; do not wear nylon tights pantyhose or tight jeans. Choose white cotton underwear, easy to observe the color of secretions, often change underwear to absorb secretions, underwear should be changed and washed frequently, wash underwear separate from adult underwear to prevent pollution. 2, when urinating legs as far apart as possible, the labia separated (can be “facing back” sitting ¾ facing the toilet), so that the amount of urine reflux to the skin of the vulva and vagina to minimize, to develop the child’s own habit of wiping the vulva. Teach the correct method of wiping: you should wipe from front to back with your legs apart to prevent the stool from polluting the urethra and vaginal opening. Use toilet paper to wipe the pubic area, because excessively soft tissue paper or poorly flexible recycled paper is easy to adhere to the vulva after absorbing water, which can form a vaginal foreign body and cause a violent rejection. 3. Wash and dry after each bowel movement during infancy, and pay attention to drying urine stains on the skin after urinating; wash the vulva every morning and evening, pushing open the labia majora to expose the labia majora and labia minora when washing, as shown in the picture below, so as to avoid adhesion of the labia minora; basin and towel should be dedicated, and the water should be clean, not using the sewage after washing and wiping. Occasionally need to use soap, then use mild unscented soap, avoid bubble bath, as well as shampoo in the bath tub; pay attention to keep dry after washing, and use wet wipes as little as possible. 4. If you find that your infant scratches her vulva, her vulva is red, swollen, itchy, her underwear is yellow, she smells bad, she urinates frequently, cries when relieving herself or suddenly wets the bed, you should take her to a pediatric gynecologist in time.
