My daughter is currently 6 and I got her ears pierced when she was 5, so she's had the studs in her ears for just over a year. I've been having a hard time getting the backing off the studs. They just won't come off. I tried, my husband has tried, even my aunt tried. My aunt said she talked to a co-worker who has a young daughter and she suggested they might be screw-on. I've tried unscrewing one of them, but it won't come off, I just keep turning the backing. Any ideas?
