My 4 yr old is always making up stories which in effect I suppose should be called lying. He has an extremely over active imagination and has 3 imaginary friends who he talks about and tells me where they are going and what they are doing. But he is coming home from school and saying things like 'Ben was sick so he went home today' and he wasnt and didnt and there were no girls at school today as they had to go to France to see the Eiffell tower. He also says things like 'Jack hurt him in the playground' and got sent to the head and I know that he didn't as I ask my older child.
Should I be concerned and is he telling lies or just letting his imagination run away with him?
