Myself and my brother were doing plenty of chores from about 10 years old (though tidying bedroom was earlier). Both our parents worked full time and my dad was in the Fire Service so worked very long hours and our help was needed. It never did either of us any harm yet I still feel guilty asking my kids to empty the dishwasher as I am at home therefore they 'shouldn't' need to help out. But, I'm at home because I'm too ill to work so need their help. And these are skills they need to learn before they're sent out into the big wide world. So, though I'm horrendous at this too, please don't feel guilty. There's no reason for them not to help out
