Tonight I have flipped at my 11 and 8 year olds behaviour. the 11 year old is rude, answers back, doesn't listen, and generally knows best all the time. the 8 year old is whiny and whinging and crying all the time. I have got fed up tonight I announced that from tomorrow on, they have to earn all screen time - for 30 mins polite/calm/not killing each other they earn 10 mins screen time. They both went to bed howling at how terrible this is. now I am wondering what the hell will happen. will I survive? has anyone else done this and lived to tell the tale??
