Viv: (screaming and rolling on the floor) But I don't WANT to go to bed!!
Me: oh! You don't have to go to bed right now. You can come brush your teeth first, then go to bed.
Viv: (calmer) But I still don't want to go to sleep!!
Me: OK. You can just lay in your bed till you fall asleep. You can just stay awake until you fall asleep. Ok?
Viv: (with a triumphant smile) Yeah! Ok!
And she trotted into the bathroom to brush her teeth, go potty, and got her PJ's on and got in bed.
Thank you, zoloft.
