I would like to know what helped the mom's out there who gave birth naturally with no epidural and advice you can give me. I am due October 25th with our first child. I have one friend who gave birth naturally and she said what helped her was watching the Lamaze classes on You Tube (still need to view them) The breathing techniques is what helped her she said.
Thank you!
