guy,
In this case, kindermusik is more suitable to your bb. For this course, you will so tired after the course as it emphasis on building up close relationship through the exercise.
As I said, they have two courses, one is for 0 to 18 mths and one is for 9mths or above.
The course named kindermusik is suitable to your bb, it mainly teach you how to massage, play with your bb. You will have home material (actually is an album).
You may try for one lesson. Personnally thinking, it teaches you how to play with your bb and build relationship with him/her. Cost is around $180 one hour.
