My SIL is Chiropractor and is trained in the Webster technique which can turn a baby from breech into head down positon. You would have to research if a Chiro in your aread can do this move. A friend of mine used moxa sticks to help turn her breech baby.

As for increasing amniotic fluid, as far as I am aware, you need to keep well hydrated with plently of rest. I don't think there is anything you can do to increase the fluid as such.
