Exercise programs are great for active kids but I am also aware of many friends who have taken their kids to Music Together classes (my kids are too old).  My friends take their toddlers to this class where they sing(moms and dads or a nanny also attend), dance and play all kinds of percussion instruments.  I have read up on the program and it seems to be a great place to have fun and learn too.  Unlike other music programs, this class is all research based and has been around a LONG time and they give you music books and CDs to take home.  The national site has a website www.MusicTogether.com so you can do the research yourself.  They used to offer classes at the TaiKwonDo Studio in Watsonville but they are going to offer classes through the Community Center during the next session in the fall.  Good Luck!
