I was told to sleep on my left side. I did it religiously with both and neither were posterior, but I am not sure if that is a fact or an old wife's tale lol
Hmm that could be an old wives tale! I slept on my L side all the way through (way more comfy) and DD was posterior!!! Yeouch.

Isadora - some great advice here. I'm interested in reading all the posts too as I do not want a posterior baby this time around either!!!! It was SO PAINFUL being all in my back..... awful!!!! (and no drugs!!).

Oh yeah, and I'm a sloucher too which I was told "after" the birth, could have caused it!!!

Good luck hun.
