I have no children to help you out on proper advice. But I will give you my story that is of the same topic. I had made a vow to myself that if i lost weight, and could see my naval again, I wanted a naval piecing. That was my treat to myself for accomplishing my goal. I went and got my naval pierced by what was "reputable", by someone elses standards. It was the worst experience, they used something that looked like a miniature harpoon, and it was dull. So i had to be poked twice. My naval was sore for days, never got infected. I had to take my ring out 2 years later for surgery, and i had so much umbilical swelling d/t hematoma that formed at the surgical site (NOT related to the piercing) that my hole closed and had to wait several months before I could get it repierced (at a reputable place by my standards). My belly has been pierced for 3 years or so and I have no regrets, again i am 40 and not a teenager living in my parents house so this story probably won't help you in the least. But at least Silverdaughter is coming to you to express her wishes/wants instead of doing something behind your back. I think that takes maturity.
