We use reward charts for our boys. We have them taped to a door out of reach but in view of everybody.
It has been simple things we need them to do- breakfast and go to kindy without fuss, get dressed without fuss, eat all their dinner, shower/ bed no fuss things like that.
We use printable sheets and start with just a tick- no fuss with stickers to start.
No its school holidays I will work out different things and for the older boy have a chore chart going Our boys make so much about everything at the moment we'd never get anything done if we didnt have the charts
