Dinah - another follow up question. Our plan, although a good one, is not working. Our daughter is now throwing temper tantrums. We send her back to her room (at 9pm, 9:30 pm) and she is screaming at the top of her lungs and will not stay in her room. Fortunately her sister sleeps through it. She has done this three times now. When she is calm the next day she knows it is wrong. But this has GOT to stop. She's 8 and way too old for tantrums.
