I'm in the same sort of situation with the long drives to get to a lot of places. If I leave the area, there is a long, straight road I have to drive down and its very easy to zone out. As nutty as it sounds, I have an out loud conversation with myself to keep the focus - "So we're driving down Gnangara Road now on our way to X. Today I need to find . . . " sort of thing.

With multiple kids I know how hard it is to catch up on any sleep during the day but if there is ever an opportunity, then take it. Even lying in bed to feeds your girls allows you if not sleep, then rest so if that works for you then try that too.

Good luck. I hope things turn a corner for you soon so you can start to catch up
