I personally would wait until my kids are older just because her ears will be so tiny and they have a lot of growing to do so the piercing can possibly migrate and she ages. Also, I love getting piercings and my favorite part about getting them is probably the relief of it being done after all the anticipation beforehand. I'd want my child to experience that feeling of "i did it" after choosing to get the piercing his/herself. Also I think that my love of piercings has made me such a good sport with getting shots lol! But anyway, that's just me and whatever you choose to do is fine! If I may though, I would absolutely recommend that you don't get her pierced with a piercing a gun, and with a proper needle instead. You can have a healthy piercing from a gun with no problems but there are many reasons that getting it done with the needle is so much safer
