L.,
Here are some ideas you can try before the ECV is scheduled to try to turn the baby vertex. Also, I would insist on an ultrasound before I agreed to a c-section to be sure the baby was still breech.
Tilt board: the head lower than the buttocks is commonly used for 15 to 30 minutes one or two times a day to encourage a breech to turn. Most women use an ironing board with a blanket for padding and elevate the end about 12 inches. The idea is to lift the baby's head out of the pelvic girdle so it has room to turn without being stopped by the bones. The best time for this is one to two hours after a meal when blood glucose is higher. That is the time the baby is most likely to be awake and active. If the baby is asleep then it cannot turn itself. You may also want to place headphones playing music on your lower abdomen while you do to tilt board to further encourage the baby to turn.
Chiropractic care: there has been great success with a technique call the Webster Technique. Here is a link with information on it: http://www.icpa4kids.com/about/webster_technique.htm
Call around to the chiropractors in your area to find one who is experienced. This may be your best option as many babies are breech if the hips are misaligned and there is not enought room for their heads in the pelvis.
Accupuncture: moxibustion is a technique that involves the out edge of the pinky toe nail and some heat. I understand that it is uncomfortable, but effective. And certainly less discomfort than recovery from surgery.
Flashlight: use the flashlight to shine through the abdomen and entice the baby to follow the light to the lower abdomen.
Cold therapy: place a bag of frozen veggies on your upper abdomen. Babies don't like the cold on their heads and may move away from it to the vertex position.
Swimming: find a pool and swim froggy style, doing periodic dives under the water (not from the side, just from the surface of the water), and do handstands. The boyancy affect may allow your baby enough room to turn easily.
Nothing: find a doctor who is willing to attend a breech birth without fear. There is a doctor in Dayton, Ohio, who I have heard is willing to attend breech births on first time moms. Also, many babies will flip on their own without interference. Babies can flip even during labor, so you may want to have them prove that your baby is still breech before you submit to unneccessary surgery for a breech baby, only to find your baby moved to vertex anyway.
I hope these suggestions help! They certainly are less invasive than an ECV and many have been shown to be as effective or more effective. ECV are typically followed by an immediate induction. They don't tend to want to wait until term over concerns of the size of the baby, so the risks of a near term baby rise.
