My daughter too, she has not cut her tooth yet but you can see it and you can't see any of the other ones yet. Her doctor said that its not typical but that there is nothing wrong with it, all children are different.
The "usual" order of teeth only works for about 60 - 70% of kids, that's why some baby books don't even list them. Any order is fine. Just think, she could dress up as a vampire for her first Halloween!
