Oh N. work on this one NOW - do not wait until your next US!!! I say this from experience - my son was most definitely breech from 30 weeks on and he never budged. :( I tried EVERYTHING to turn him.
A few resources for you:
www.spinningbabies.com - great info on helping baby positioning
Also try knee-chest position several times per day for 5-10 minutes at a time. Try swimming. Try the breech tilt (lay with your hips above your head and try and relax. Try putting frozen peas on your babies head. Visualize your baby turning head-down. Put your ear phones low on your pelvis and play music. Talk to your baby.
I also went to Dr. Nella at Bucktown Chiropractic - she does the Webster Maneuver which has been shown to help breech babies turn. My midwife recommended her.
Most babies at this point will turn around on their own before the birth, but it never hurts to give it a little help. The longer you wait the harder it gets for the babe to turn because there's less room.
If nothing works by 37 weeks you can try an ECV (version) where they manually turn the baby. I tried this. Apparently it works about 50% of the time. Didn't work for me. It wasn't painful I didn't think.
If for some reason the baby does NOT turn you do NOT HAVE TO HAVE A C-SECTION. One month after I had my son, ACOG revised their guidelines on breech birth. They now say that it is AS safe to v**inally birth a breech baby (as long as it's frank breech) as a normal one IF you have someone who is experienced in delivering breech babies. Mostly this will be older OBs since the art of delivering a breech baby is somewhat lost on the younger generation.
Good luck! Please feel free to email me if you have any other questions. I ended up with the C/S and now I have to deal with VBACs for the rest of my life :(
**************** Update in response to a few messages I've gotten about this *************
First of all, the abstract and reference for the ACOG revised guidelines:
Obstet Gynecol. 2006 Jul;108(1):235-7.
ACOG Committee Opinion No. 340. Mode of term singleton breech delivery.
ACOG Committee on Obstetric Practice.
In light of recent studies that further clarify the long-term risks of v**inal breech delivery, the American College of Obstetricians and Gynecologists recommends that the decision regarding mode of delivery should depend on the experience of the health care provider Cesarean delivery will be the preferred mode for most physicians because of the diminish-ing expertise in v**inal breech delivery. Planned v**inal delivery of a term singleton breech fetus may be reasonable under hospital-specific protocol guidelines for both eligibility and labor management. Before a v**inal breech delivery is planned, women should be informed that the risk of peri-natal or neonatal mortality or short-term serious neonatal morbidity may be higher than if a cesarean delivery is planned, and the patient's informed con-sent should be documented.
******************
Second, I haven't personally sought out a physician who can deliver breech babies v**inally, but a paper from the 1980s that involves nearly 400 v**inal breech deliveries was authored by Dr. Edmund Confino, currently at Northwestern (and specializing in infertility). If I had to start looking for an experienced practitioner I'd probably start by asking him.
