First off let me say I am not against home births or VBACs. However, I would like to offer some info that I hope you'll consider when making your decision. (I'm not trying to be a hater - just offering some sound advice :) )
Has your OB told you whether you are in fact a candidate for a VBAC? The reality of your situation is, depending on how your first birth went along with other contributing factors, you may not even be able to consider having one becuase it's just too dangerous for you and/or your baby. Now if you are a candidate and want to try having a VBAC - go for it!!!!! But I STRONGLY recommend that you consider having it in a hospital or a center where there are medically trained personnel (not doulas or midwives) available. If you were to try and do it at home and your uterus ruptured or tore, or your muscles weren't strong enough to deliver your baby and labor was delayed, you would need immediate attention by a doctor to control the situation. Either situation, or many others that are possible with VBAC are so dangerous and I couldn't imagine gambling with the health of my baby just to be at home.
I'm sorry that your c-section scared you. I had one 10 months ago (first child) and I was surprised at how little discomfort I had - granted mine wasn't done during an emergency, just after a LONG attempt at delivering and before my son started to decline. My cousin just had her 3rd child by csection and she said that it was a completely different experience when you schedule the birth. In her words, "You check in at noon and by 2 you have your baby! No problem!" So consider that - no stress, no wondering, just a little prep work and before you know it your baby is in your arms :)
Both she and I delivered at Adventist Health Medical Center (Portland/ Mall 205 area) and they have a FANTASTIC birthing center - private rooms, sleeping area for dad, great staff! They also offer alternative birthing methods that involve water and natural elements. And in case you need a doctor, Dr. David Sargent, who's office is right across the street from the hospital, is AMAZING :) He is a wonderful and very experienced man!! He is also a huge advocate of natural births and VBACs.
Good luck!!!
PS - I work for an attorney who specializes in birth trauma cases - I'll leave it at that.
