Nevertheless I understand the notion that most of us brazilians have that tu is more formal than você, since most of us only see tu in grammar books, poems and songs. Actually even in present-day love songs - like the sertanejo musical genre - the use of teu(s)/tua(s) is very common, mainly due to this notion of tu regarded as a pronoun for poetry, and thus more refined and aesthetic.
It seems the difference is not just formality, it's also a matter of politeness. In an area where "tu" is commonly used it may be impolite to refer to someone as "tu" until you're given a signal that you can do so. At least that seems common in Portugal where you'll hear "Por favor, não me tratas por você", for example. Using "tu" with a child is not a problem, though.
