“It has to do with how much baby skin leads onto the umbilical cord from the baby’s body. Less skin makes an innie; more skin makes an outie.” About 90 percent of people have innies, and the rest are outies.
One may also ask, what determines an outie belly button?
The belly button outcome is random. Once the umbilical cord is cut, the cord will dry up and fall off. … The most popular explanation is that the difference between innies and outies is due to where the umbilical cord is cut and that extra skin left from the umbilical cord may cause the protrusion of an outie.
Thereof, is it rare to have an outie belly button? The majority of people have “innies,” the very scientific term for belly buttons that dip inward. Protruding “outies” can be found on approximately 10 percent of the population. They’re about as common as left-handedness.
Just so, can an outie become an innie?
An outie cannot become an innie but it does go in once the muscles in the abdomen grow stronger and the hole gets healed by itself. The hole usually closes within 12 to 18 months but takes longer if it is bigger.
