Rupturing is a bit of a myth. Until about the year 2000, VBACs were the norm and then suddenly that are considered dangerous but there isn't much, if any, research to back that up. If anything its another way hospitals are trying to avoid lawsuits. My midwife and I were just talking about this today. I've never had a c-section, but my sisters have. She said that the scar tissue is even stronger than regular tissue so rupturing is not very likely at all.
I am about 4 weeks away form my due date. I chose a homebirth because of scientific research that I have looked at over the last five years. I know that my midwife can handle almost every complication that a doctor can. She said if the placenta separates from the wall before the baby is born, or the cord comes out before he does, then I have to be transferred, but other than that, she can handle things herself. The advantage is that she will let me get into whatever position I want, take more than a day to labor without being induced, eat and drink, and give birth in water. She has over 20 years experience and averages at least one set of twins each year. I feel very safe in her hands, and if you choose your midwife carefully, you can feel just as confident about a home birth.
My family thinks I'm being naive to think I can handle labor pain, and many think I am endangering my child's life, but research doesn't support those attitudes. I don't think I would do it if my husband didn't support me, but I recruited him by sharing books and articles with him. Perhaps you can convert your husband by sharing what a midwife can actually do, and how home birth has many advantages, and is safe. Once he sees the research he may change his mind. Your Mom may never support the idea, but I think all of us have friends and family we just have to smile at who think we're crazy when we say "birth at home." If the birth goes wrong, they'll say "I told you so," and if the birth is managed well, they'll say "you were just lucky."
Ultimately I feel that a woman should give birth wherever she feels most comfortable and safe, so if a home birth is scary to you, you might not have a very good experience. If you have birthing centers nearby, that may be a great alternative, provided you find a midwife who is truly supportive of your plans and has experience with VBACs.
