R..
I got my DD's done when she was about 9 months old. We never had any issues with her pulling. I paid $10 at Walmart (I got sick of hubby procrastinating taking me to a tattoo place, where I wanted to take her because they have MUCH stricter regulations on piercing equipment... so I got them done while we were grocery shopping. lol.). That included the earrings, piercing, and ear-care solution. The I kept the piercing earrings in until this month, because I just haven't bothered to switch them. My DD cried for about 30 seconds, then I distracted her and she forgot about them. She has NEVER had ANY issues with them whatsoever. I would use a q-tip dipped in the solution to clean the front and back every morning, before and after her naps, and before bed until they healed. The piercing earrings are really good about not losing backs, because they click into place. They are actually kind of hard to get off... lol. But so far I have also had luck with regular earring backs, I just put those little clear rubber stoppers on behind the back to help hold it on, and keep it from poking her.
I absolutely LOVE earrings on little girls. I think they are adorable.
