After the newborn’s belly button falls off, it is possible to take a bath in about 3 days. If there is bloody or purulent exudation or redness around the cord, it is not possible to take a bath. After 3 days of shedding, most of the umbilical cord stump is dry. In this case, it is also recommended to use a belly button patch to protect the umbilical cord from water, because after water, the local area is moist and bacteria can easily breed and cause infection. If water is accidentally introduced, use clean gauze or towels to absorb the water to avoid infection. After a month of bathing, the umbilical cord stump is completely dry and the skin barrier is stronger, so you can stop using the belly button patch and dry the umbilical cord completely after bathing.
