Many, many babies are still breech at 33-34 weeks, but it is also a great time to start trying to turn them. Here are some things that she can try:
Pulsatilla in 200c or 1M strength. If 200c, every 2-3 days, 1M once per week or so. The 1M is probably a lot harder to get locally if there isn't a homeopathic-specific store.
Webster technique a la chiropractor.
Moxibustion, either at home or at the acupuncturist.
breech tilt exercises -- pelvic tilts on a slant board, like an ironing board leaned up against a couch or a huge amount of firm pillows to mimic the same effect.
Swimming, especially doing upside-down maneuvers like diving from the surface to the bottom repeatedly.
Visualization, application of heat, cold, light, music in an effort to either annoy the baby away from its current position or lure it to a new position (like putting a strong, bright flashlight up next to the lower belly so that baby checks it out, or dold packs up top so that baby moves away)
A version can be a good last resort and if done by a skilled provider can be effective and carry a small enough risk to be worth it as a last resort. Many of the practices in my area do versions at 38 weeks, so if the same is true for her, she has a month to try other methods.
Good luck to her!
