Under normal circumstances, the umbilical cord will dry and fall off naturally about seven to ten days after birth. The newly detached belly button will ooze some blood and water, so it needs special care. Whether the umbilical cord has fallen off or not, the treatment of the belly button is divided into the following two steps: 1, every day after the baby’s bath, be sure to dry the water in the belly button. 2, the last with a cotton swab dip 95% of alcohol applied to the navel, from the root of the umbilical cord (or concave) outward to the skin, and in each diaper change, check whether the umbilicus is dry; if the umbilicus is found to be wet, we must repeat the above actions (to 95 percent of alcohol wipe again). 95% alcohol is to accelerate the drying of the navel, rather than sterilization, the umbilicus is dry, it is easy to fall off, and less likely to breed bacteria. Also less likely to breed bacteria. The concentration of alcohol used for general disinfection is 70%, which should not be used for the care of the navel area. When the umbilicus is expected to fall off, it should be treated in the same way as described above. Be careful not to pull the dry umbilical cord that has not fallen off as it may bleed. Be careful not to treat the umbilicus with iodine, ointment, sesame oil or unknown powder.
