DD2 (10) is addicted to her tablet. I let her have a couple of hours a day but it's starting to drive me mad when I ask her a question and she barely looks up from the screen and it's clear she isn't listening. Anyway she was in her room this morning so I went to get her to suggest we play a game together. I walked into her room and start to speak and she suddenly explodes at me saying "I was just charging my tablet and now it's not working and it's ALL YOUR FAULT!!!" I asked her to calm down but she grabbed my arms and flew into a rage, her face turning red. I said to her "go and sit on the stairs and calm down" but she carried on screaming so I shouted "do you WANT a smack?" I was at the end of my tether. I would never smack either of my children but I felt I was very close to it. She ran off to the stairs crying and then told my DD1 the whole story, obviously playing the victim. I then get DD1 saying "Mum, how could you say that to her? You promised you would never smack us". I explained she had been very rude and I lost my temper. Funnily enough they are the ones usually hitting each other and screaming! I did apologise later but feel terrible now
