we dont have set jobs but they are expected to help around the house, my rule is we all make the mess so we all help clear it up!
so they are exepcted to keep their bedrooms tidy, the littler ones get help with this.
put laundry in the wash and then help fold laundry and put it away.
set and clear the table.
the elder 3 will help hoover, wash up, sweep the floor etc.
the elder 3 again help cook, ds1 can cook meals on his own, ds2 helps chop and prepare veg etc and can cook with supervision.
basically they are just all expected to pitch in as and when asked, so when ds1 gets in from school (he gets home about an hour before i get back with the little ones) he will do any washing up in the sink, or tidy sitting room and run the hoover round etc.
i dont expect them to do all these things everyday but they help out as and when :)
they are 12, 10 today! 7, 4 and 18mths and even the littlest one will tidy toys etc, she tries to help with laundry as well...
