I was originally going to call this the "overnight hat trick," but realized it doesn't apply if you have more than 3 kids.
Of course, on 2nd thought, "hitting for the cycle" implies four, so there's a more encompassing analogy, but I should really get to the point, no?
The idea is this:
If you have a night where you are woken up a different time for each of your children (in my case, 3), then you have a 'hat trick' or have "hit for the cycle."
There are nights where I get up and two kids are up at the same time, but the worst is where one gets up, you settle her, go back to bed, and the process repeats..and repeats.
It's the exhaustion that gets you more than anything.
