Where do start, my son has an issue with everything i say, saying its the wrong tone etc. hes very argumentative throwing things when he is angry,swearing at us etc. he has taken to spitting when he is having a tantrum which he says he has to do or he will smash our faces in. I find he gets annoyed with almost everyone about the most trivial things which dont even matter. and the other day he says the smell of my coat made him want to kill himself as it reminded him of a boring Sunday!!! Do you think this is normal behaviour?
