Infants should take good care of the navel area before the umbilical cord has not fallen off or shortly after it has just fallen off, and keep the skin clean and dry, which can be cleaned and disinfected with hydrogen peroxide, or disinfected with iodine vapour and de-iodized with alcohol, followed by covering it with sterile gauze or using an umbilical cord protector, which is very helpful in preventing and treating infections in the umbilical cord area. If there is redness and swelling around the umbilical chakra, you can also apply anti-inflammatory ointment such as Bactroban as appropriate, which can promote the local inflammation to subside. During this period, you should pay attention to the use of the child’s diaper, avoid covering the umbilicus, so as not to cause urine soaked umbilicus caused by infection. Generally, after careful care, the umbilical cord will fall off in about 10-15 days. At this time, continue to clean the area 3 times a day to keep it dry, and the umbilical node will soon be completely healed.
