Hi ZeldaGirl,
I know you've said you've read all the books and tried it all, but have you tried Love and Logic? I can't stress it enough. It works. I will PM you this great resource I found online that summarizes the main parts of the program so that you don't have to buy the whole book.
The main components of it are: limited choices (choices within reason), natural consequences, and consistency. You offer between two choices that you will be happy with such as: milk or orange juice, peas or corn, red shirt or yellow shirt, brushing teeth now or in five minutes. You say everything very calmly and clearly. There is no yelling. You choose several one-liners to use such as:
would you rather
probably so
this is so sad
I love you to much to argue
Here are some sample conversations regarding choices:
Mom: Would you rather have peas or corn for your vegetable?
DD: Neither!
Mom: Only little girls who eat their vegetables may have dessert
DD: No!
Mom: This is sad....when you have decided which vegetable you would prefer, let me know...
And if she doesn't eat her veggies, follow through and do not give her dessert.
Mom: Would you rather have milk or orange juice to drink this morning?
DD: NO! I WANT CHOCOLATE MILK!
Mom: (calmly and sweetly) Your two choices are milk or orange juice
Daughter: I SAID CHOCOLATE MILK
Mom: This is sad. I don't want you to be thirsty, so when you're ready for milk or orange juice, let me know.
Then turn away and go about your business.
She will soon learn that if she doesn't choose between what she is offered, she will suffer the natural consequences..no dessert, going thirsty etc...
The main thing is that you and your husband have to be 100% consistent with this. The first couple of days might be tough and she tries to test you and break you, but persevere and you will have a new kid!
Good luck!
