There are a number of different methods out there and I think all would be great to educate yourselves on preparing for childbirth but just wanted to share that I just came back from my Lamaze Prepared Childbirth class and it was great! Highly recommend it. If you want to look into it, the DC area website is a good place to start: https://www.lamaze-dc.com/index.htm
By the way, it's a huge myth that Lamaze is all about breathing (and unnaturally at that...."hee-hee-haaaah" style).
