I had my ears pierced when I was 6. I had two more ear piercings when I was 14. I had my belly button pierced at 18, my tongue pierced at 21, and two tattoos at 22 and 26 respectively. All the piercings and tattoos were reflections of my personality and self-expression (although at 6, I could have waited a few years and arguably wasn't able to comprehend the event) and so I am also curious as to why parents would make that choice for their little babies. To me, it seems to be more about the parents (seemingly from many of the above posts, the mother in particular) and not about the little girls.
hahaha I'm so not listing my past piercings

I had my ears first done when little, with a gun and had nothing but problems and took them out. I wanted to have them redone in year 11 and went to a qualified piercer and never had a problem.
