Would i be overwhelming my child by sending him to enrichment class (Music Class, Gym Class ) at such a young age?

I think exposure to music lessons are good since it is something that requires expert guidance. However, if your child does not appear to enjoy a particular instrument, it may be good to try different ones to find one that interest him/her naturally. With regard to gym, I think while it is good for the development of a baby's motor skills, many of the activities could also be accomplished through play. Still, I have friends who have sent their babies for such classes and found it fun and enjoyable for their bubs. They feel that the activities also helped promote social interaction with other children. In all, I feel that as long as your child is not feeling stressed out from these lessons, some of the options may turn out to be unique experiences for a child and will make his/her childhood fun and interesting. :)
