Now that the kids are a bit older, they usually sleep through the night or have just one wakeup. Our son goes down first usually, and then our daughter goes down an hour or so later. So my sleep window starts at 9 or 10 pm, and goes until I wake up at 6 or 7 am.

That's a ~9 hour sleep window... I usually spend about 5-6 hours of it sleeping (the rest of the time is for work and chores). Then once a week or so, I'll fall asleep while putting my daughter down and sleep the whole 9 hour sleep window.

What's your sleep window look like these days?
