They even did some night duty last night, though I stayed up later with Jet as he'd had a three hour nap during the day and was up late. I finally got him to settle a little after 10, and I went right to bed and couldn't sleep well until nearly 4, when Jet got up. I put him back to sleep, and was finally able to go to sleep when he got up again... this time George came up and got him.
I slept in until nearly 8. Tired. Harder to sleep alone than I thought it would be. Maybe I should just move Jet into my bed, not have any anxiety about waking up when he does, and just hand him over to his grands after he gets up in the morning. Of course, that wasn't until 7:30 this morning... so I'd be late for work, but so it is.
