Don't patronise the kids.

Don't trivialise the music.

Don't put down THEIR (peer-group) music.

Encourage them to listen to ANYTHING - and be ready to do the same yourself. (Norma Waterson gives great credit to the fact that her family listened to a very wide range of music).

Make sure they get some of the BEST folk-related performers to listen to.

Encourage them to perform, together. If you've got some reasonable musicians get them working "by ear" (not a skill that ranks large in a more "classical" musical training).

Treat them as fellow human being and work at having good relations with them; kids rejecting their parents' music (or what they see as such) is most often far more a rejection of the parents than of the music!

Be far more ready with praise than with criticism, and constructive with the critisism you do offer. And if you're going to offer criticism make sure you're ready to take it, too!

Accept you ain't going to win them all and don't get despondant.
