Not interested in this discussion because it's been done a million times before, but I have a 'public service announcement' that is related.
DD is 8 and does not have her ears pierced. She wants them done and I have said no until she is 10.
We went to a 'posh' wedding in Sep. DD was a flower girl. All the bridesmaids had their ears pierced, so I allowed DD to wear some clip-on's from Claire's. They were diamanté style, almost like disco balls. She wore them from about 1400 until 2200. They were only small.
When she finally took them off she burst into tears (and she's not a kid that cries easily). Her ears were dented and bright red on the lobe. She hadn't complained of any discomfort during the day, only when the 'pressure' was released.
Over the course of the next day her ears developed what looked like 'love bites' - red and black spotty bruises. These took over a week to go, and her ears were still painful whilst they were there. Sleeping was rotten because every time she rolled onto her side she hurt.
I spoke to an assistant in Claire's (not to complain as such, just to warn) and she said that in her opinion (not the shop policy) their clip earrings were too tight for little kids and should only be used by teens/adults. I'd agree with her.
So, just a warning in case you have compromised and allowed clips over piercings.
(Bonus for me was that DD hasn't once asked for her ears pierced since this happened, whereas it was at least a monthly occurance before)
