How old would you let your kit get there ear pierced ?

i have four piercings in my left ear and one one my right. I was a baby when my first piercing was done then when i was in my grade five? i don't actually remember if its grade 5 or grade 4 when i got my second one. I was the one who made all the piercings because i am quite scared if someone will do it for me. Happy mylotting!
