Operation Single Sleeper, Regression

Last night, Camille woke up at 1am, which is business as usual. Normally, she goes right back to sleep.

But last night, she didn't go back to sleep. She stayed up crying until 4am.

I'm. So. Tired.

I think she's teething. She had better be teething, because otherwise she was screaming for 3 hours in the middle of the night for no reason. And if that's the case, she's grounded.
