Thanks everyone for your thoughts so far, really helpful. I've got the name of the person I need to email at Northern Ballet so I'll see about the boys class, thankyou Balletchick, or perhaps one on a Sat morning. JulieW, I think sadly Tring is too far for now, you're right - a shame because I understand they're really good.
That's really interesting feedback Harwel - was that Northern Ballet associates class on a Friday or an RBS one? I'm really sorry to hear it put your son off. Has he carried on dancing?
Snape, that sounds fantastic, I can hardly wait!!!!
Thank you everyone, this is all great advice
