Linguistic snobbism in its early stages

You may think that kids who grow up bilingual somehow adapt a correct pronounciation of both languages, just like that. I'm afraid I'm gonna have to disappoint you.
This is an authentic conversation that I overheard from the back of the stroller today at the zoo (please note that everything, apart from the name of the animal in question, was uttered in Swedish):
Adam: Look, mom! Mankeys!
Florence: It's not mankeys, it's moonkeys!
Adam: No, it'f not, it'f mankeys.
Florence: It's pronounced mOOnkeys. Not mAnkeys.
Adam: Nah-ah, it'f jeally plananced mAnkeys!
Florence: Moonkeys!
Adam: Mankeys!
Florence: MOONKEYS! MOONKEYS! MOONKEYS!
Adam: MANKEYS! MANKEYS! MANKEYS!Florence and Adam - good friends most of the time.
