Birth classes

Temp782982187506089

I took the Rex class when pg with Owen and it was ok, I definitely don't want to take it again or feel that I need to.  I really want to find a class that is going to teach me more about relaxation techniques, and the actual labor.  I know there are Bradley method classes, but I highly doubt I will do a natural birth.  I was induced last time and had a rough time pushing because he was still somewhat high and the epidural didn't work so I couldn't focus through the pain.  Any ideas if there are any classes that are just on labor preparation?  Would Bradley be worth it?
