She should be fine. The siblings to ours developed about 4-5 days quicker than our littlest one did. So they were playing rough and developing teeth before her, so she couldn't fight back. I would hear her cry out a few times before I realized what was going on. I ended up having to separate her out when the playing got too rough until she caught up with them and could fight back. I would always put her back when everyone was eating or sleeping. She became really attached to me though, because I was always rescuing her. But that didn't hurt my feelings at all....
Anyway, I just wanted to mention it so you could make sure her siblings don't hurt her if she gets her teeth in later than they do. It wasn't long before she could keep up with the best of them after those few 'catching-up' days. Can't wait to see pics!
