Mine are the same age hun and I am about to create some charts for them. I don't think they are too young to contribute to the family. They need to learn and see that is normal for them to have to pitch in and share even if it is simple things like making their beds, emptying the cutlery tray from dishwasher, tidying up the play room and their rooms etc. I haven't decided about what to do with pocket money yet - I want them to learn that as part of this family they are expected to pitch in and help out, more and more as they get older but I don't want it purely linked to treats/rewards at the moment! Will let you know what I am going to do once I work it out
