My OB was teling me about this - he attended a session on it at the hospital recently. He thought it sounded great but didn't want to make me his guinea pig. I'm lucky that bubs is positioned well and that I've got great support to avoid being on my back so hopefully I'll avoid the pain of a posterior labour. I am starting to feel a little apprehensive about what the pain will be like but I guess it will all be over in 36-48 hours (I'm due to go in for induction tomorrow at 5pm if nothing has happened). I'll ask around at the hossie to see if anyone has had the injections.
