I was looking at some maternity pics and noticed this one where her belly button hasn't "popped" (at least, yet?)
Does everyone's belly button pop out eventually? When does that usually happen?

Also, I have a belly button piercing and just noticed yesterday that the bottom hole used to be tucked in the belly button (like under or hidden?) and now it has kind of lifted up and I can see the bottom hole! eek! I wonder if it will go back to normal later. I don't usually wear a ring in there anymore, but the double hole looks strange to me. hahah
