i remember seeing a lady posting here and in natural birthing session that had a breech birth story in her signature.
i think breech birth can be done vaginally as well, you just need to find a supportive doctor/midwife for it. they now push women into c-sections mainly because they're not trained for delivering breach as much as standard vaginal deliveries, but if you find a supportive doc i'd definitely try that route before opting for a c-section.
so many people were born breach vaginally when we were kids, or 40 years ago and such... good luck with everything!
