Zizi in French means willy... (useful word in my mother tongue, I admit).
My DS would be constantly playing with it or showing it in any public place (last time was in a middle of a big family dinner...) if he could!
Notwithstanding the constant embarassment, I am getting really fed up telling him off all day long. please tell me this doesn't last until boys are 15 or I'll have a nervous breakdown!!!
