Question
The newborn was 26 days old when a white tubular object appeared in the original umbilical cord opening, which later turned yellow. The parents are worried if this is a normal occurrence and how to handle it.
Answer
Based on the description, the newborn’s umbilical cord opening may not have fully healed yet, and the white tubular object could be a remnant of an umbilical catheter. It is recommended to use iodine solution for disinfection to prevent infection. This is a normal process, and the catheter will eventually fall off on its own. Parents can seek the doctor’s advice for examination and necessary treatment.
