I think she needs to do some service for this woman to make up for her incredibly rude behavior. Clean her house or do some favor while she is there, and as long as she is acting this way, there is no reason Julie should have to drive her to appointments, friends' houses, etc. Until she appreciates the service she shouldn't get it except for basics to keep her alive and healthy. If it came down to it I would ultimately take away the books, but only if this other stuff doesn't work first. I hope that helps, I just feel so sorry for this woman having a 9-year old act that way would be so degrading. Another idea would to be to tell her that you are taking the vacation money you had set aside to take her to ____ and giving it to the babysitter as compensation for dealing with such a terrible work environment. Meanwhile, get her started on learning a second language so she can see the effort that it takes. If you take it easy on her now, she'll never learn. As for correcting the babysitter on the other two children, if she has an issue she should take it up with you as you did the hiring, she has no right to boss around someone that you left in charge. Ok, I think I covered it.
