The time it takes for the umbilical cord to fall off varies from person to person, usually 7-10 days. Some newborns shed their umbilical cord later, but usually not more than 2-3 weeks. The shedding of the umbilical cord is related to a number of factors, including the tightness of the cord ligature, the thickness of the cord, and the ligature site. If the umbilical cord is thin or the ligature site is close to the root, it will fall off earlier. Under normal circumstances, the umbilical cord can fall off naturally in 5-7 days, but in some newborns, the umbilical cord falls off later. As long as there is no purulent discharge in the umbilical fossa, no obvious odor, and no redness or swelling around the umbilical chakra, it is not a big problem. A small amount of bleeding and discharge can occur during the shedding process, and it is recommended that the umbilical cord be disinfected with iodophor on a regular basis. In addition, parents need to keep the umbilical cord clean and dry when the umbilical cord is still intact, and use umbilical patches to avoid water ingress. After the umbilical cord has fallen off, it is important to wipe the navel area with a clean towel to keep it clean and hygienic, and to change the child’s diaper regularly to prevent infection.
