Enrolling my son in a karate class for 2-4 year olds.

What can I expect from this class?

What should the uniform be?

Do I need to start looking for a white suit? If so, where would I get one?

Marketing genius? This class is two days/week for $20/month...I dont think they are making a whole lot of money on that one.

My town is limited on activities for smaller children. This is the only thing I can find for his age group. He will not be fighting other children. He will be learning basic discipline (which he needs) I did not ask this question to get rude answers...I asked it because I know nothing of karate or any martial art for that matter and was hoping for some honest responses. So thank you to the first 3 posters for ruining this for me.
