Updated to say: Thank you Diana!!! It worked! After posting my desperate plea for help I popped her in the tub, scrubbed and scrubbed and scrubbed, let her soak a while and scrubbed some more. It lightened it up drastically but it wouldn't have taken a very clever person to figure out what had happened ;). I just tried out the suggestion Diana left in the comments and Bethi is now as good as new, and now I can truly appreciate the humor in the situation ;). Bethani thanks you as well, Diana...now mommy won't be catching her every time she runs by to rub some more hoping to speed up the wearing off process :). My oldest daughter (who is really such a big help but can't quite remember that Bethani is not as short as she used to be and is often leaving such things as markers where it could be gotten by little fingers...) suggested using the Mr. Clean magic eraser because it did such a great job on the floor and chair but that just didn't sound healthy to me...
I find the tiny dot on the tip of her nose especially attractive.
That's permanent marker gals...any ideas?
I am trying to focus on the humor in this situation.
