The principle of umbilical cord care for babies is to keep the area clean and dry, and to disinfect the periphery of the umbilical cord with iodine povidone before the cord falls off. When using diapers for male babies, it is important to pay attention to folding back part of the top edge in the front to avoid covering the diaper to the umbilical cord, so that sometimes urine will wet the umbilical cord and cause contamination. In addition, the umbilical cord has not fallen off the child can not be put into the bath tub when bathing, to separate the upper and lower parts of the wash, the umbilical cord part can not touch the water, the child’s umbilical cord in most of the 7-10 days to fall off, some can be delayed until more than 20 days. Sometimes there may be blood seepage when the umbilical cord falls off, and there may be a small amount of blood after it falls off completely, which is normal. Dry the blood with a sterile cotton swab, disinfect it with iodophor, and then dry it with a dry cotton swab. After the umbilical cord is detached, do local care 3 times a day to keep it dry. After 3 days, it will grow back and the child will be able to take a bath in the tub.
