I don't think the children have sole responsibility for anything-such as laundry. One of the things on the website spoke of the mom up late at night exhausted from doing the laundry.
I hate to disagree, and I may be completely wrong, but the mother doing laundry up late was way back years ago when they only had 5 or so kids. If the program a couple of nights ago is recent, and they have moved into their new house, so I think it is, the mother was talking about the kids different 'jurisdictions' and jinjer (12) had the laundry chore on her own, others had different jobs to do all over the house, some of them I don't think should be given to kids.
I agree when the kids reach 6+ they tend to do their own thing, but when they are saddled with chores as big as the laundry, cooking, cleaning bathrooms, surely it's time to draw the line???
