Hi I have a son who is 6,i am concern about his tantrum,unsure is it normal?He get upset by throwing tantrums i.e crying and shove things away when he hear he isnt a winner,when he plays game he always want to be a winner,even though he lost.This often happen when he plays games with friends,or at birthday party,or running race after school with a friend at home.I am exhausted in dealing with it,ran out of ideas and solution.I am so worry if this kind of behaviour continue when he grow older wander what he will turn into.Please advise.
