I think you need to pay her. 老貓, is it OK for her
to tell other kids' parents about it? I am a mom and I would really appreciate being told about this kind of thing. Think about the poor child. You can also post reviews on the Internet about it. In other words, you should do all you can to let other people know that her homecare is not good. (Depends on how much money and time you have, you can file civil lawsuit against her for child abuse.)
