Disinfection of the umbilical cord for newborns is mainly done with hydrogen peroxide and iodophor, 3-4 times a day before the cord falls off. The umbilical cord will fall off in about two weeks, and the disinfection will continue for three days until the umbilical cord stump is dry. If you give your newborn a bath before the umbilical cord falls off, protect the umbilical cord with umbilical patches to avoid infection caused by water. If a small amount of water enters, use a clean towel to absorb the water as soon as possible after the bath.
