I find myself doing this too. My kids put such a large constraint on my free time that between work and family I only have 3 hours or less per day to do everything, so I am tempted to sacrifice sleep to gain a bit more book reading, side project, or video game time.
I always had my children with me when I was doing 'me things'. Including reading, video games, woodworking, hunting, hiking, and even meditation. For reference, I'm a super introverted person, and really need alone time to recharge my batteries.
It's a nice way to instill values while also enjoying them while they're small.
I mean, they will grow up eventually (really fast actually) and won't want to hang out with you at some point, so even if you "can't" do your 'me time' with them, you will have access to it again, eventually.
I do try... with some success. My kids are still very small though so they get bored after a few minutes if I am reading out loud from anything other than a children's book. We are still in the "high entropy" stage of childhood with most of our kids.
Anything outside I include the kiddos but I'm playing DOOM and Sekiro right now so I can't exactly have a toddler watch me decapitate demons/samurais and I'd rather have a beer etc. after the kids are sleeping. When they get older we'll probably play some Mario Kart/Minecraft style stuff together.
My 'me' time is exclusively after the kids are sleeping anyway.
From just reading the headline, I thought this article was going to be about little kids refusing to go to bed! I get so frustrated when my toddler won't go to sleep, exactly because it cuts into that precious free time.
