Does a third-time mom need childbirth classes?

I’ve had two healthy babies at Alta Bates Summit in Berkeley. Both times leading up to the big event, I took childbirth prep classes. The first time was a multi-class series held over a number of weeks and the second was a quickie afternoon refresher course. Read more about my childbirth prepping and child-birthing on Babycenter.com today. My current birthplan is “give me the epidural as soon as possible and try not to deliver in the car.”

So, I’m trying to figure out… should I take another prep class?

Through the Parent Education Center, Alta Bates Summit offers monthly sibling prep classes and a range of childbirth prep classes including VBAC and a new online series. Birthways offers many new parent support classes including childbirth education; what I didn’t find is a quickie refresher for a mom like me. If you’re a member of Kaiser, their basic childbirth prep classes are free; since I’m not, I can’t tell you much.

Dear readers, what should I add to my repertoire of birthing knowledge? Are there any classes you’d recommend? Is there a place to send my husband for a “just in case you have to deliver this baby in a car” class?
