I am a Waldorf mom of 2 girls, although I have very very strong feeling about no media, I have shown my girls 'Cats' and 'Riverdance' on dvd. When my girls were younger they watched them maybe once per month, in the last 2 yrs, maybe twice a year. They both attend dance class (creative movement with a Waldorfish 90 yr former prima ballerina). They got a kick out of both these dvd's. 'Riverdance' is fantastic, exposes the child to a wide range of dance. My 6 yr old wants to start Flamenco dance instruction next fall.
These dvds have no ads and no 'characters' for them to copy. In fact it has exposed them to different dance. They create their own dances with bits of this & that thrown in. I play fiddle music for themsome evenings while I cook dinner, I moved the kitchen table out of the way and they perform!
So there is my suggestions, BTW, their teachers have no problems with either of these dvds. I also have a sitter ( a 16 yr old waldorf student) who performs and she knows the entire score from Cats, and she sings to my dds. I also have a mom who's dd used to attend our Waldorf school, she was a dancer in the original "Cats" on Broadway in NYC, my dd LOVES this women, calls her 'the Cat', lol!
