I told my DSS age 3 not to do something and he said 'shut up'. How should I handle it? He's generally been fine, but is being increasingly rude and stroppy now he's hit 3! I told him its not nice to say that. He does it to everyone, not just me. His dad generally ignores the rudeness. Should I ignore, just keep saying to not talk like that. I personally find it unacceptable and would tell my DS off if he was to talk to me or anyone like that.
