What is 'normal' at this age? He has quite a temper when things don't go his way. He is argumentative and pushes our buttons constantly. He sometimes will try to cause a scene in public to get his way. He can be aggressive and bang doors. He has hit himself as part of a tantrum. Not sure if this is attention seeking behaviour. He can't accept when we say no and then sulks and whines etc. Any ideas on how to turn this around? TIA
