Yep - the student midwife I met up with a few weeks ago was talking to me about it. I'm not sure where she is training (Maybe Geelong based?) but apparently they all gave them to each other in class not long ago but used saline rather than sterile water. Apparently it doesn't have the same bitey sting as the sterile, and wont have the same affect. So they are doing it as part of their courses now which is great.
I think Geelong hossy started doing it not long after Jenna was born (bloody typical.....) and she is 20m old now.
Chelle - its my opinion (and I'm not by any means an expert on this ) but if I had been able to get up and move around during my labour with Jenna, I may have been able to get her to dislodge herself from whatever she was stuck on. My back labour had me on all fours for about 2hrs, at home and then in hossy, so I was just stuck and couldn't get off the ground. BY having the epi I was then on the bed and things sort of spiralled down hill from there.
Perhaps all I would have needed was 10-20mins upright to get labour going again, but it was just too hard to even straighten my back up.

Blackbird - great that your PB knows about this, but someones gotta be a guinea pig right? And rather someone else than you during your first labour
