The usefulness of this attribute ended about 10 years ago, when I became a stay-at-home dad. As a parent, the survival skill is to sleep when your kid sleeps. Sleep is important. It's important to you and your kids. You need it to make your thinker work well. They need it to help their brains develop and assimilate all the stuff they're learning. A lot of ASD kids have sleep issues. Apparently, they don't produce melatonin the way the rest of us do, which means that their systems don't recognize that it's time to snooze.
With my typical kid, I would wake up early (but after 5:00 generally), thinking about things that needed to be done. I'd go make coffee, shower, and play World of Warcraft until my son woke up at oh, say, 7:00. It was all me-time up 'til then. Ah, the good old days.
Bed time was kind of fun, too. We'd sing a song, read a book , make up a story about adventures with Princess Aurora and her dragon. There was one summer when we put his mattress inside an old camping tent and he slept in there. It was pretty smooth sailing.
When Ben came along, things changed. He didn't want to sleep. He would wake up in the middle of the night. He wanted to get up and do stuff. As parents, I think we were doing all the right things -- keeping a routine, a night light, comfy pajamas, background noise (cool-mist humidifier), etc. It just didn't work all the time.
Lovely Wife and I split up the responsibilities. If there was Ben action any time after, say, 4:00 a.m., I would not be able to sleep anyway, with my morning-brain, so I might as well get up. If it was earlier than that, she would generally take over and try to bounce him back to sleep. This wasn't every night, but often enough to be exhausting.
Travel is the worst though. Sleep disruptions always occur when we travel, and there are other people to worry about, and no basement to retreat to.
