Generally it will take about 2 year of class, and over 10 years old. Because people who allowed under 10 years old, cause a great deal of trouble later. Like knee and back trouble. Its real cute to see a very little girl on point, but you better change school, because your teacher is very wrong. Hope thats help...god luck.
No, I am not a pro ballet dancer, but I do take class when I was younger. I did about 13 years of ballet, in one of the first school of ballet here in Montreal. I love it very much, and I start at age 17 with the little girls of 6 or 7. I fell strange with the very young children...but I want to know so much about dancing...well it's just great...Keep on dancing... bye bye!
