Goodbye to diapers?

One certain not-yet-2.5-year-old refused to put on a diaper at bedtime tonight. FLAT OUT REFUSED. Hmmm... She's very well trained during the day. We're working on naptime, and she doesn't wear a diaper then anymore (but still has accidents maybe 50% of the time). But this was a first at night. I didn't think we'd tackle night training for a while. We'll have to see how this works out. I'm fairly certain she's going to be soaked at some point in the middle of the night, and again in the morning if she still refuses a diaper after getting changes. But maybe she'll surprise me.
