Ok never mind. I see he's a week old so it wasn't ready yet.
It may have been about ready to fall off. How old is your LO? Also don't be worried if it bleeds a little once it does fall off. I noticed a little blood when I would change my LO's diaper and got freaked out but later found out it was ok.
I put a onesie on him so he doesn't pick at it! @valerie_jean @amiliz06
