Looking back to my own childhood I remember being 10 when my mum first handed me the sponge and fairy liquid to do the washing up. I can't remember if I asked to do it or if she forced it on me *snort* but from 10 onwards I would help out often with the chores, and from 13 I was washing my own school uniform.
Although I did get fed up with it at times, I'm glad my mum started me off relatively young. It equipped me well for university life and subsequent adulthood, after all there's no getting away from it and you have to start sometime right?
Do your children help you with the chores? How old were you when you started doing them?
