In general, healthy full-term newborns do not need belly button stickers, newborns are generally 1 to 2 minutes after delivery to tie the umbilical cord, after 7 to 14 days after the umbilical cord slowly drying, until it falls off. You only need to pay attention to local disinfection and care before the navel falls off, wait for the scabs to fall off, and there is no need for special treatment after it falls off. When the umbilical cord is not detached, you need to lift the umbilical ligation site when cleaning and disinfecting, and use iodophor swabs to rotate and disinfect from the inside out with the root of the umbilicus as the center.

If there is discomfort, it is recommended to consult a doctor in time, it is recommended not to use the navel patch by yourself according to the situation, so as not to aggravate the symptoms and induce infection.
