Umm weird question?about piercings?

So I have both my nipples pierced, I have a strong feeling I'll have to take them out but, do I have to? Are there rings that are safe for baby? Or at least something that will hold the piercing holes open?Will it be hard to put in and take out during breast feeding? Painful?If I do take them out...Will they close up? I've had them for 4 years. Looking for pierced moms with experience, I got these after my first born So I'm not quite sure.

Thanks in advance!
