The stump of the umbilical cord formed after the umbilical cord is tied at birth is called umbilical scab; most of the umbilical scabs will fall off on their own in about 10 days after birth, but the time of falling off may vary due to different factors. Most umbilical scabs will fall off by themselves about 10 days after birth, but if the baby’s birth weight is small, the umbilical cord was thin in the womb, and the doctor tied the umbilical cord nearer to the root after birth, the umbilical scabs will fall off relatively early; conversely, the scabs will fall off later. Before the umbilical scab falls off, pay attention to protect the umbilicus, you can use iodine povidone to disinfect it 2~3 times a day; try to avoid contact with water when taking a bath. There is no oozing around the umbilical fossa and the skin color is normal. If there is oozing, redness and swelling, there is inflammation, which needs to be treated in the hospital.
