After the newborn’s navel has just fallen off, there will be a small amount of blood or pus discharge in the navel fossa for a short period of time. Parents can use a medical cotton swab dipped in Amyl iodine to disinfect the navel fossa 2 times/day until the discharge disappears, usually about 2-3 days. During this period, the navel should not be exposed to water, and the child should be cleaned again with a cotton swab after bathing. In the case of boys, urine may splash into the umbilicus when urinating, so parents must pay attention to keeping the navel clean and dry locally. If there is an increasing amount of purulent discharge from the belly button, or if there is redness and swelling in the umbilical chakra, this indicates secondary umbiliculitis, and this situation must be seen in the hospital. If the belly button has healed and no discharge is generated, it can be dipped in water.
