Ok, in a fit of exasperation I plonked 2 empty jars on the kitchen windowsill and told dd(5) and ds(2) that they needed to get 8 pieces of pasta in their jars by Saturday night otherwise they will not have the usual sat night takeaway. DD has transformed and was very helpful this morning. Now how do I carry this on all week and what are the rules? I have told her that I will take pasta from her jar for naughty behaviour. Also how do I include a 2 year old in this?
