We have a rule that the kids wipe up after dinner. We have a mixed house, some kids who live with us full time, some part time.
One thing that keeps coming up is that some kids are out at friends more than others so don't do their wiping up when it's their turn often meaning that the child who did it the last night does it again.
This is causing problems in that the home birds feel they are being penalised by having to do more wiping up.
I thought a rota might be the way to go? Although I don't know how that would work in reality. I'm sick of the arguing every night.
