Most reputable tattooist will be very wary of tattooing a person under 18, even with parental permission, so I would be particularly wary of a tattoo at this young age as the quality of the work would potentially be poor. DH was 16 when he got his first (back in the day it was easier ) and as a result I have told my kids if they wait until they are 18 I will pay for their first. I personally waited until a few days after I was 18, but it was the same design I had wanted since I was 13 and I still love it now so I guess tastes don't always change but in children the chances that they will and the tattoo will be regretted is bound to be higher.
