So recently my older skids (4 and 5) have started lying to get each other in trouble. One will do something wrong and both of them will come running to me saying the other did it. It takes a long time to get the guilty one to confess. They end up sitting in their room or at the kitchen table for long periods of time. I feel bad because I know one of them hasnt done anything wrong and they're still being punished. Any suggestions?
