Frances has taken to waking up between 3:00 and 4:00 a.m.
At first, the early waking would happen only once in a while. Then, it became weekly. Now, it is happening at least three nights a week.
When she wakes up, it’s for the duration of the day, too. She goes through the rest of her day and evening without showing any signs of tiredness.
Keeping her up later didn’t work.
I have no idea why it’s happening, or if her sleep pattern is changing for the long term.
