What is the reason why the umbilical cord of a child has not fallen off one month after birth?

Patient's question:

No

Doctor's answer:

It's a normal phenomenon that the length of the hair left during childbirth varies, and the baby's constitution is different. However, there is one thing that is certain: it's safe. The latest it falls out is 7 months, so please don't worry. Also, don't mess around, as it's easy to get infected. Just keep it clean.
