C.D.
We have been doing Music Together for almost two years and started when my daughters were very young. It was fantastic when they were infants - they loved the music and watching the big kids. It is fantastic now - they love participating with the music and seeing the babies who come to class.
We are not in the city, but here is a class locator for Music Together Classes.
