Naw, I would pass on it. You already know what labor and delivery is like. What is to refresh from that? I did Lamaze with my first child. What a stupid waste of time it was for me. All that huffing and puffing didn't do a darn thing to distract me from the pain. When I was pregnant with my second child, I bought a book about the Bradley Method. I read that book and studied it with my husband and I have to say I enjoyed it so much! It's not like Lamaze with "special breathing" exercises. I did my first two pregnancies (labors) without drugs but still ended up having c-sections for both anyway. There are plenty of resources online to help you "remember" what you might have forgotten, but most women don't forget much about their labor and delivery. IF anything, they know what not to do, what to do next time, and what didn't work at all. Good luck with whatever you decide.
