Everything Hazel suggested! All of those were wonderful resources for us. We took a Bradley Method Class before our first homebirth (our 2nd child). All of what we learned carried over not just to our 2nd homebirth (third child) but to our 4th child's hospital birth. The deep breathing that Bradley teaches significantly reduced my pain.
I will tell you something about the 4th baby :) Assign the others a specific task before the baby is born, something they will be responsible for to help you rest and heal. My oldest was 7 1/2, he could hold the baby on the couch, or sit next to her bassinet so I could take a shower (he'd come get me if she cried) as well as make a sandwich and tea. The next in line was only 4, he was a silly kid but played well with his younger brother, so he helped that way. My youngest was 23mo, and he was my 'fetcher". He was smart as a whip with a great memory, so he was the one to get me diapers and wipes and other simple things I might need.
Each of my homebirths was an amazing experience. It's where I felt safe, and I had the best births at home. But what I found was just having a dedicated and loving midwife meant that no matter what happened, I would have her support and guidance.
I also feel the need to give you some stern advice :) Do not do too much too soon. Being at home gave me the impression that I was on the fast track to healing, and I remember complaining to my midwife how much my abdomen hurt about a week after the birth. She scolded me for going up and down stairs too much. Heal at your own pace and accept help. Take care of you so when you can get up and resume your regularly scheduled programming, then you will be doing it as a healthy mom.
Also accept the fact that, if something goes awry, you might need to go to the hospital. Homebirthing means accepting a small amount of risk concerning life-saving measures during a birth, but midwives are trained to see signs to avoid unnecessary complications. I know two people that had to be transferred, and one fought it the whole way and had a traumatic birth experience. The other woman trusted her midwife and went without a fuss, much less traumatic for everyone. You can only control so much. I say this because many of us have homebirths so we can control things we can't control in a hospital, and that's true, we can. But there are things out of our control, and having a conversation with your midwife about emergency protocol is imperative.
Happy birthing!
