Boobs post partum: do they go back to how they were before pregnancy? The shape, nipple shape, aureola size and color?

Please don't make fun of me! 😂
I had my boobs done in 2009 & my aureolas made smaller. They're now the size they were pre op and I'm just curious to know other's experiences. Do our boobs go back to how they were? What about after breast feeding? 
I imagine everyone's different but please share!
