Of course it can work the other way. Sometimes the last thing a young person wants is encouragement from parents.

Sometimes being told it's tuneless rubbish can be confirmation that it's worth doing; being told it sounds great means there must be something wrong with it.

Young folk musicians come in two flavours - those with parents who love folk music, and have encouraged them all the way; and those who are into it in face of parents who think it's total crap.

I get a feeling that a lot more of the second sort are starting to emerge. That is as well, because there are a lot more people in the last generation like that second bunch of parents (who think we're crap) than there are like the first (who are us.)
