It does seem geared to WAHMs. A couple of ideas: maybe you could split the chores up between 7 days, instead of 5? The weekends seems to be relatively free as is. Also, could you delegate some chores to a partner or older child?
DH and I share SAH/WOH duties (we work opposite shifts). He does a lot around the house, but is NOT a follow-a-schedule person. He does more of the ongoing tasks, like dishes and laundry. I want to do better at the stuff that's more *MY* thing, but last time around MMs became an exercise in futility if I wanted any one-on-one non-cleaning time with my kid.
I kind of want to e-mail and ask about a "lite" version... like same tasks, only more spread out over the entire week and perhaps the tasks come along a little less often so that there are fewer (assuming this will lead to a slightly decreased level of cleanliness, but still, consistent) each week, but the site strikes me as very... um... what's the word... I don't know, exactly. Like a WOHM wouldn't be well-received. Or maybe I'm just paranoid .
