I have it clearly stated in my contract that rates may increase yearly in January when the contract is reviewed and renewed. That way it is no surprise to anyone if I do raise them. That being said, since I just started in March, I am not planning on raising the rates this year for anyone, but likely will the next year. I also stated the amount it may go up by. I think this is pretty standard, but the key is that the parents are aware of it and have agreed to it by signing the contract. Plus, I started out charging a fair rate, so I have no need to raise it immediately.
