Just thinking, what if twice a week, you ask your husband to take charge of the later hours stuff, and take a mini sleep vacation, taking a couple of extra hours on let's say a Monday and a Thursday?
My weekly luxury is staying up later on Saturday night (sometimes all the way to 11pm!!!) and I'll just sleep until whatever I want on Sunday morning. Surprisingly, I only sleep maybe an extra half an hour to an hour. For the next couple of days, I feel like I'm more rested.
I think it's partly because I don't set an alarm on that morning (or Saturday either)
