How to care for the umbilicus of a newborn: 1. If the umbilical cord has not fallen off yet, you can lift the stump of the umbilical cord and wipe the root of the umbilical cord with 75% alcohol from the inside out, about 2-3 times a day, for about 3-4 days the umbilical fossa will remain dry and not prone to umbiliculitis. 2. If the umbilical cord has fallen off, you can use 75% alcohol to lift the dry scab of the umbilical fossa and use the same method for care. Generally, umbilical cord care can be performed at home and will not lead to umbiliculitis in newborns if care is in place. If the umbilicus is oozing, whether it is bloody or purulent, and is accompanied by redness and swelling around the umbilical chakra, the newborn is already showing signs of umbiliculitis and should be seen in the hospital in time to prevent local infection from causing systemic infection.
