Honestly gals, there are some webster certified chiros who are just not very good at turning babies, I've seen them
So maybe try another webster chiro? icpa4kids.com has a provider search and they list out webster certs in their list, you can search by zip to see who is close to you.
I did my own version at home with ds. My dd was head down and stayed down, though she was a bit crooked at birth. My ds was head down and flipped breech and stayed breech at 34 weeks. I saw a webster chiro 3x/wk for the first 2 weeks, then 2x wk, and at 37 weeks I piled up all my couch pillows and did the "ironing board" upside down thing every night for a few nights until I could feel ds float up out of my pelvis while I was upside down. Then I put my fist in under him to keep him from dropping back in, and gently petted him in one direction (with "a mothers hands are always gentle" advice from my midwife friend in another country) as my mantra.
I felt him nudge and budge and nudge a little more, so I kept moving my fist up along my abdomen under his butt until he was transverse. Then I slowly rolled the way his head was and sat up, and he kept rolling. He stayed head down at that point.
I don't know how well it would work on a 1st baby, but a 2nd with a stretched out uterus and abdominal muscles was pretty easy, just took a long long time and a lot of patience. It was much easier on him/me too, since there was no anxiety of the hospital, no meds in our bodies, no time clock, no pressure.
I would have gone to the hospital for a version at 38 weeks and was in contact with a midwife who was willing to do a vag breech home birth too.
In hindsight, I'm lucky he flipped, he's the kid that "statistics are made of" - with a 44 cm head, he was the biggest head my midwife had ever measured (and she's caught babies for years and years and years) and would have likely been the one that "breech babies should all be sectioned" came from. chin first it's likely he would not have fit.
