You can occasionally squat to wash your buttocks for a short period of time during the month, and it is not recommended to squat for a long time. During the monthly period, the size of the uterus has not yet recovered, and the ligaments and muscles at the perineum are relatively loose. Occasional squatting will not cause discomfort, but prolonged squatting may lead to pelvic floor tissue prolapse, such as uterine prolapse, vaginal wall prolapse and so on. For women with perineal incision, prolonged squatting will result in high tension on the perineal incision, which may lead to incision pain and poor healing of the perineal incision. In the first week after delivery, most women need to wash the vulva with a non-irritating antiseptic solution to keep the vulva clean. This can be done by lying on the bed with a healthcare worker or a family member. After the stitches are removed from the perineal laceration, the mother can sit in a sitting position and rinse the vulva with warm running water. Do not take a sitz bath and do not douche the vagina. During the puerperium, keep the vulva clean and consult a doctor if there is any abnormality, so that appropriate treatment can be given under the doctor’s guidance.
