The umbilical cord usually falls off on its own about 7-14 days after birth. There are individual differences in how early it falls off depending on the ligation method. Generally, the umbilical cord will fall off on its own within 14 days of birth. Parents should pay attention to the care of the umbilical cord of their newborns. They can use 75% alcohol or iodophor daily to care for the umbilical cord of their newborns to avoid infection of the umbilical cord. If the umbilical cord is thicker, it may take longer to fall off naturally, but parents should not worry too much. If the umbilical cord does not fall off for more than 14 days, and the skin around the umbilical cord is red, swollen, with elevated skin temperature and purulent discharge, you should consider the possibility of neonatal umbiliculitis and go to the pediatric surgery department of a regular hospital as soon as possible to have the umbilical cord manually removed and treated for umbiliculitis by a professional physician. In addition, the baby needs to pay attention to umbilical care after the umbilical cord falls off, and avoid making the child cry as much as possible to avoid excessive abdominal pressure, which may cause the crusted area to ooze blood.
