I think it's Natalie at her Hot Pash shop. www.hotpash.com (I'm hoping I can put in the address for you cause she's a bellybelly marketplace member. )

When I had DD - 9 years ago - they didn't have them. I just took it out and got it repierced. With DS, I just took it out and decided if I wanted to redo it, I would. Fortunately when he was over 12mths old I had a look and I could get the bar back thru it.
