Well, thanks so much for all the stories ladies! It really is helpful to read through them, and realize there's a heap of healthy mums and babies out there who have birthed posterior babies, though it may have been a little more difficult.
Those of you who had particularly long labours or ended up with c-sections - were you encouraged to change positions, etc? Were you allowed to stay active in labour? A friend of mine laboured for about 2 days on her back with a posterior baby, before someone told her to try getting on her knees. I thought that was ridiculous! She had a doula with her next birth and everything went MUCH better.
Samantha - yes, I was confused by that too at first. I didn't know it made a difference to be on the left or the right. But if I understand it correctly, the baby should be facing down at birth, and experience has shown that babies tend to move clockwise. So instead of simply tipping his back up and his face down, he will likely move back down first, then to the left side, and the to facing down.
If anyone knows why that happens, I would be curious to know the reason!
I guess there is a chance he might go the short distance, going counter-clockwise, but that is not so likely, from what I understand.
Anyways, thanks again, and I would love to hear more!
