Kaz, we went on the weekend, and I was 31 wks then. We are going again to another one in two weeks as well. We had the option of going every wednesday night for 5 weeks or 7 weeks or something, but we chose the full day option as we thought it would work out better for us. Our class was pretty full on, and it was mostly the educator talking, showing pictures, watching videos and getting our partners to massage us, a tour of the delivery suites and stuff like that - not a huge amount of time for discussions, though we did get to have some time for discussion. I guess if you go to the one spread out over a number of weeks you'd get more time for discussions and stuff.
When I booked in to the hospital, my midwife gave me a pamphlet about the classes and they said to go to the claases from about 26-28 wks onwards, if we choose to go.

At the class, the midwife did say something about how people might tear if they have epidural because they might push to hard (so bub might come out too quick for you to stretch) because they cant feel the area, so they dont know they are pushing too much until the midwife tells them to push less. omg did that make sense? I am having trouble with thinking today.
