When did your daughter get her ears pierced? Or did she has?

I've seen babies get their ears pierced not too long ago after being born. I was one of those babies -- my grandparents were super old-fashioned and they believed that piercing my ears early would be better than waiting till I was older because it wouldn't hurt so much. I don't know how true this theory is but personally, I'd wait till my daughter is older, maybe 6 or 7?
