It's good to get the views of others on the rates. Keep in mind that we all do things differently and decide the amount and frequency of our own rate increases. You need to talk with your provider. Whether we think it is a big increase or appropriate or not is not relevant. If your contract states that your rate stays the same until Sept 2013, then you need to remind her of this point. If she disagrees then she is going against her own contract and you need to make the decision to either try to negotiate with her, pay the new rate, or look for care elsewhere.
