I hope this is a troll question, because if it's not, you are really NOT the person to be having kids let alone parenting them, judging by this question. When I was 6, the thought of a tattoo never crossed my mind, however I did admire the beauty of them whenever I saw them on someone. When I first found out about the pain of a tattoo, that really scared me, to the point where whenever I saw someone with one, I thought they were a tough broad (this was when I was a child). Even as a 6 year old, I knew they were a permanent decision, though I found out about laser removal later down the road (and people say that hurts FAR worse than a tattoo). The kid is going to change her mind, have new interest as she ages (she may like ponies but chances are, it will be something else later on), and regret has no age limit. Remember that, plus can you imagine a 6 year old getting a tattoo?! Kids normally hate shots when they're at the doctor's office, imagine 4-5 needles jamming ink into your child's skin, 3,000 times a minute! Besides, I am currently getting a tattoo on my wrist next month for my 18th birthday and I wanted it since I was 14. My mother promised me she will never sign for me to get a tattoo and if I did, I will be old enough to sign for it on my own terms. What do you know?! I'm signing for it next month, my mom sure wasn't playing around!
