Don't call me stupid

Yesterday, Jack was upset because I had said movie time was over. He really cannot regulate his emotions around screen time. Every Friday, we allow him a movie or video game -- usually for no more than 1 hour. Every Friday, when it's over, he freaks out. He screams. He cries. It doesn't matter that I remind him not to do this before movie time starts. So yesterday, in addition to the usual drama, he called me stupid. He has said this before and I have told him not to do it. We were supposed to have ice cream last night and after he told me I was stupid, I told him that was not ok to do. It is mean and disrespectful. I told him I would never call him stupid for those reasons (and for others obviously). We are introducing the idea of consequences. The consequence for calling me stupid was that we cancelled ice cream. He was upset about this but after a while, he understood. We'll see if he does it again. I said 'don't call me stupid' several times. Each time I thought of Kevin Kline's character in A Fish Called Wanda. It made me feel silly. Being a stern parent does not come naturally. That said, don't call me stupid!
