Help! Does anyone know of anyplace in Western Suffolk that does a breastfeeding class?

I had signed up for a breastfeeding class at Good Sam and just got the paper in the mail with the dates. They scheduled it for a Sunday afternoon and I have a friend's baby shower that day.

I either have to find another class or go to the shower an hour late. I did not pay for the class yet so I can still switch to another class if I can find one.
