Bet that updated contract threw her for a loop. She realized just how lucky she was to be on the old contract and it will be interesting to see in the next few weeks if she bides by it totally for fear that you will make her use the new one - hence the fed and dressed, change of clothes, etc. as stipulated in the contract. Good for you for standing your ground. And even if she does leave because she annoyed you can bet she will likely start out on a different footing with the next one so you have done all caregivers a good deed.
