DS1 and 2 are driving me up the wall with their bickering and winding each other up. normal consequences/ignoring not working, things getting worse and worse. i have (possibly shot myself in the foot) and said they have lost all screen time and have to earn it back . now no idea how to monitor this: maybe 'if you dont argue for half an hour you earn 10 mins of screen time' or similar? but i will need a chart for each child wont i?? anyone got any experience of making this work? help!
