Thank you ladies for so much valuable input.
I've made up my mind in 2 ways:
1) I will deliver in a hospital
2) I will not change my OBGYN.
I hope all of you have wonderful births. I know all of us will choose what's best for our bodies. I know myself well enough to know that the above 2 items mentioned are best for me.
Happy Pregnancy Mammas=)
I also wanted to let you know that there is an EXCELLENT CD set sold by Hypnobabies that helps women feel more confident about their twin pregnancies and births. It's an excellent way to help you overcome or at least minimize your fears, so you don't have unnecessary stress interfering with your pregnancy or happiness at what should be a really wonderful time in your life.
If it turns out that you do need a c-section, there is also a great CD for preparing yourself for that as well. It even has handouts talking about ways to minimize trauma and risk for the babies if surgery becomes necessary. And of course, there is also the wonderful childbirth preparation home study program that could help you learn more about the process, and understand all the choices you have along the way, and how the risk/benefit ratio fits your situation. And it also gives excellent information on avoiding or minimizing tears.
Good luck with a very healthy, happy pregnancy, birth and life with your obviously much-loved twins!
