I have been practicing the skills we learned on Sunday. Tonight I had a small victory - my son dumped out two games with lots of pieces on the floor before bedtime and I calmly was empathetic and explained he needed to clean up or no book at bedtime. While he tested me at the start and we did a time out - he came back and cleaned up both games without my help and was able to have a book at bedtime. It was the first time I held him accountable and it felt really good!
As you advance in skills you'll move up to the Uh Oh Song and Bedroom Time as possible consequences. See my website for more information on those:
For those of you with older kids it would be more appropriate to use "Energy Drain" although it's possible to use this technique for younger ones as well.
