Bad attitude...

I thought it was just teenagers that went through the bad attitude stage but a quick survey of parents tells me it starts much, much earlier.  I have proof!
Ok so he was actually impersonating Ben 10 here which is strange because I think he's only seen the program once but he has Ben 10 colouring books and stickers - could the attitude have stemmed from here?

The "I don't want to wear this' Attitude - could it possibly be because he has a vast amount of clothes to choose from?

Is he destined to be an angry boy?

Or is it all just a stage?
