When he's not traveling DH does all the meal planning, food shopping and cooking. So that's 50-75% of the time.
When he's away I quite often order pre-cooked food for the family so I don't have to cook. Or I get each teen to make one meal that week.
My kids have school dinners - I long ago gave up making lunches.
As I said above everyone does their own laundry. I don't tidy their rooms or nag them to do it - I leave them to it. DS's room always has overflowing baskets of clean clothes. He's happy so I leave him to it.
We share things like cleaning bathrooms, vacuuming, dishes, feeding animals, emptying bins. Whoever didn't cook clears up dinner.
They don't make much mess in our shared areas so there isn't much tidying to do, but if you have a toddler then I remember how it feels endless.
Mental load is shared much more evenly than it used to be. It's pretty common for DH to be emailing or calling the school about stuff for the kids even if he's working 1000 miles away, or researching holiday ideas/flights.
He manages this alongside a very stressful job, because he doesn't have the option not to, I guess.
He also does a lot of DIY but that can be pretty stressful, and we are starting to outsource that more eg we recently had someone install a window for us, where in the past he'd have done it himself.
The kids do stuff like mow lawns and help with bigger gardening jobs like spreading a trailer full of mulch, chopping and stacking wood, taking out trees.
Looking at this, I'm wondering what I actually do...
