It's now seven am, and just the dog and I are up.
The thing I need to remember is that this is not the basis for some kind of ritualistic compulsion to repeat exactly what got me here. Sometimes, a person just gets a good night's rest, and sometimes a person just needs her mom for a lot of hugs all night long. I am not actually in control of this situation.
I should not form a new religion around that time I only woke up once overnight after a long stream of waking up much more often than that. (I think it was five days, but it felt much worse.)
The husband and the cat typically both sleep less... thoroughly than the dog and I do, but then I don't know what they were up to at three or four am, because I was asleep then. I was asleep all night long, except for one time at like 1:30, when I was needed to provide a snack, which I did gladly.
And now I'm a little bit more ready for when I wake up every 45-90 minutes all night long again tonight.
