My DS is 17 months. Last night he spent his first night binky-free. He cried for about 5 minutes and wimpered for about 45 minutes. But he had an exhausting day and I knew he would eventually give in to sleep. Any advice on how to get him to go to sleep without his binky at naptime? I'm fairly sure he just won't go to sleep. (He's done that before when he's thrown his binky out of the crib.) How long do I leave him if he doesn't go to sleep?

I don't know if anyone is on right now that can help, but thanks for any advice you can give!
