I do want to see a game in the future have the dad be home and the mom absent, just to switch it up a bit.
Well, that would be anti-traditional. Doesn't the mother always stay home (stereo-typically)? Maybe grandparents? The mother and father would be... gym leaders (double battle a la Tate & Liza in Gen III)? And they would be home at night-time, seeing now that there are different parts of the day.
