A small amount of mucus or purulent discharge from the stump of the umbilicus

The umbilical cord is a channel for the fetus to provide fetal nutrition and fetal waste in the mother. After the fetus is born, the umbilical cord loses its physiological role. The ligation of the umbilical cord usually occurs naturally within 3 to 7 days after birth (or longer, depending on the method of umbilical cord breaking). The wound is red and slightly moist during the initial cut of the umbilical cord. An umbilical fossa is formed, and a small amount of mucus or purulent secretion from the stump of the umbilicus indicates that bacteria have invaded the umbilical fossa and inflammation has formed.
