Thank you!!!!!! @jjsmommyjj711 yes his stump did fall off way too early I believe it was pulled by all of the family holding him! I found it in his onesie after one week old. Thank you for responding I believe it will need the silver nitrate as its not oozing like most articles say

it's a pice of his umbilical cord. ..it might have fallen off to early like my son's and left a little spot that still needed to dry on ,my son need a few silver nitrate treatments to have it completely go away ,it's harmless it just stains thier onsies . his doctor might want to get an ultrasound done to make sure nothing is poking through like his bladder and such.
