My DD is the same as yours - she would rather spend more time and effort avoiding work than she would expend actually doing it. We call her Lazy Lucy LOL and I gave up long ago trying to encourge her to help out by using a rewards system or pocket money because she will quite happily forgoe money or treats if it means she doesn't have to help around the house. So after a big screaming match one day where we both totally lost the plot, she is getting better. She understands that when you live in a house with other people that you are expected to do your fair share of the work. So everyone gets in and cleans communal living areas together and everyone is responsible for their own room inc making beds. They also put their clothes away once they have been folded (Maybe that is the extra thing you can add?) and they have to unpack their schoolbags each day. Luckily I have DS1 who is a cleaner LOL and DS2 is going to be a cleaner too I think. DS1 will go above and beyond his 'set' chores and help out DH on the farm, shifting sheep, doing welding, cutting burrs, anything DH is doing that he can help with really. But he also gets a heck of a lot more pocket money and treat items too. I don't see it as favouritism that he gets more than the girls, I see it as him doing work that he gets paid for kwim?
