Most of the umbilical scabs fall off normally between 10-15 days and the umbilical roots dry after they fall off. If there is a little pus after shedding and the umbilical cord is old and yellowish red, and the umbilical cord is not red and swollen, the baby can generally wipe the navel at home with iodine volts twice a day. If there is more pus after the umbilical scab is shed, and the umbilical cord is red and swollen, and the baby has fever or no temperature, and is not responding well to milk, then pay attention to the possibility of neonatal sepsis, and take the baby to the hospital in time.
