We did Bradley and were very happy with it. I'd look at your local library and see if they have any books/videos about the Bradley Method. Its possible to educate yourself at home, though the class helps a lot. Working on the nutritian aspect and the streches are very important to get your body ready for this "athletic event" of birth. All that can easily be done at home. The most important part about the class was learning about all the interventions, their risks and how they are helpful - so YOU make the decision about what you want to do. This doesn't mean you don't listen to your doctor, but if they say do you want this or this, you can know which you'd rather do, or if they suggest something you can say, hey what about trying this first... It just is very empowering. I'm sure the books cover this stuff as well, its just not in a conversational type environment. The last thing is learning how to relax. Bradley does not do rhythmic breathing like Lamaze does, however learning to take long deep breaths and focus your mind on something helps A LOT!!! I watched the clock to time my contractions, after 30 seconds of them getting stronger they ALWAYS started to decline at that 30 sec. point - even if that part took a minuet or longer. Its really like a marathon, you gear up for the long haul, but also focus on getting through each small step as well.
Your husband will be invaluable if you go with this method. Be sure he's in touch with your birth plan (he's supposed to be like the guard dog, answering questions for you and such so you can relax, and keeping people from bothering you while you labor) and knows ways to massage your back when you're uncomfortable. My husband struggled through this part, he's very jittery (hyperactive, not worried) and drove me crazy until my mom gave him a laptop to surf the web with. ;) However, he was great during the pushing stages. We need to practice more relaxation techniques for this 2nd time around since my family might not be here to help us.
If you have any other questions please let me know I'd be happy to explain anything to you! Congratulations on your pregnancy!
