I have taken my now 15 month old son to both the dance and gym which are free for him. It seems he already like the gym better and so we stuck with that for now, maybe in a few months we try dance again. Ms Caroline is very fun and tries to really interact with the children to get their groove on.
Jumping Genie (?) is the gymnastic instructor and makes it fast paced. It took some adjustment for my boy to get used to, but he seemed to like it better last time, so we keep moving. The only thing I wonder if they sanitize all the toys after each session, especially during flu season as they were just left there and not separated out.
