Not sure if you are interested in dance/gymnastics for excercise or development. For the most part, starting dance at 3 will not make or break your daughter. Girls that truly have an interest will be fine starting around 5 yrs old. All that being said, if you are ok with beginning "shuttling" your child to dance beginning at the age of 3, go for it. As far as recommendations, it depends on what you are trying to do. Classical ballet studios, Tuzer and Chamberlain. Other ballet studios that Miss Melba's and Toby's school of dance. Personally, I am a classical ballet girl but it really is up to your own preference and what your overall goal.
