I've only started ballroom relatively recently, and although my scores for footwork need work, I nail expression and presentation everytime. I don't know why, but my friends firmly beleive it's because I've been obsessed with old movies and musicals all my life and havesubconciously absorded thestyles, mannerisms and flavor. I've only had brief stints of lessons in other dance forms throughout my life and now wish I had paid more attention, since so much of all techniques carry over in to ballroom. Starting your child in any movement class to encourage her desires will only help build her self confidence, love of her own body and personality and social skills. I'd find a basic movement/dance group for pre-schoolers, there will not be a lot of technique for a while at that age, but there's plenty time for that later. I'd also use this as a great oppertunity to keep music and dance alive in your house, renting musicals, dressing up and dancing around the living room etc... Have fun!
