This will sound awful but I’m really struggling with my 11 year olds behaviour. He is just so rude and mean and it’s all the time he is also extremely negative, always tries to cause arguments or look for problems. He constantly fights and argues with his siblings and just tries to constantly upset people. My other children are not like this so I don’t know why he is but it’s making it very hard to get on with him and be around him. Has anyone ever experienced this? Does it get better?
