I think all around +
there is not a right age to start dancing but the best age to start is 2/3 years old.
Never.
Whenever she feels ready to start her career for her older age maybe a young age!:)
At US Tennis Open places.
The best age to start reading to a child is from infancy, as early exposure to books and language can have a positive impact on their development.
As soon as possible.
As young as possible.
Well it depends on how mature you are. Also if you want to go to the Olympics I would say start around 4. If not maybe 7-10 would be best. Remember you can start a sport at any age.
There are no age limits to start ballet as each studio differs but it is best not to start too early, six is a good age to start at if you want to be a professional ballerina
after you have finished growing
8-10 years
