Can you do any work, admin or relaxation on your commute? I know the last one might be counterintuitive, but when I had a 4+hr round trip commute, I would use it to sleep, watch TV or do work, to either relax or free up my evenings.
While kids are young, I really think you need to claw back time where you can’t and where you can’t, accept that for this season, most of your time is spoken for.
Even just having a hot shower for more than a couple of minutes (or without kids!) is a treat for me for now, but it won’t always be like this.
Also, can you cut down on “dinner” (at least the prep and clean up part, by lowering expectations or throwing money at it)?
Best case scenario, I’d do extra work on my commute in, half and half on my way home (something mindless or interesting like a podcast or TV on the second half of the trip), easy dinner, and no work after kids are in bed. If it means delegating more at work or buying in more help, so be it.
