Has anyone else got a 3yo with a foul attitude? Occasionally he's happy but tends to only be when he's getting what he wants and he can snap out of it in seconds, then is suddenly fuming about everything and even his favourite things can't act as a distraction. He has started to be quite rude to us and relatives, shouting to go away/be quiet and refusing to say hi/bye etc. Is this just a phase? He's been a relatively happy child up until recently. We do have a 4mo baby too so wonder if he's still adjusting. Sometimes I think he's playing/acting putting on an "angry " face but then most of the time it seems he's genuinely angry. Other 3yos I know don't seem to have quite the same sort of mood swings so just wondering what others have experienced at this age?
