Both my sister and I had ours done when we were about 4 months old. Neither of us has any issues with eveness or infection.

My sister chose to wait until her girls asked. My eldest niece started asking for them at 2 years old, all the time. My sister held out until she was 5. She is now 13 and loves them still. Can often be seen looking at earrings but with her skin sensitivities, she can only wear good quality earrings which my sister can't afford. She loves birthdays and Christmas as my mother and I often get her earrings.

My youngest niece got them at 5 also. She decided after a couple of months that she didn't want them so they closed over. Next birthday she changed her mind and my mother (with my sisters approval) got them done. This time she loved them and can often be seen changing her earrings because she loves bling. She is almost 7 now.

I think it is a personal thing. I think they look cute in girls but I have 2 boys and I do not like earrings in young boys.

I would not go against my DH though. If we have another child, and it is a girl, then this is something that needs to be mutually decided. My DH is very traditional so I would expect that he would defer to me anyway.
