@joleneoxo, I had my daughter with her shots in order to get her ear pierce if she didn't then it would of been complicated. you have to know how to pierce the ears and be very careful because they have a vain in a certain area of their ear. so yes they have to have their shots or they can get a fever.
I dunno, sorry Hun. I'm sure another mommy would have the answer you're looking for though. There's moms on that don't vax. You can make a post of your own asking, try google also, and/or talk to her Pediatrician. @joleneoxo
I'm not getting my daughters pierced, so I'm not speaking from personal experience. I believe after their first round of vaccinations or so, if you're getting her vaccinated that is. And before they start grabbing their ears. Also, see if your doctors offices offer that service.
