There are 4 types of breech positioning; Complete (kind of like siting cross legged but knees up), Frank legs up by ears, footling or kneeling. If baby is complete or frank VB is possible.

ECV is External Cephalic Version where they try to turn baby from the out side. the procedure is U/S to check position and a CTG, some times they give a drug called a tocolytic to relax the uterus. the woman lays on the bed and the doctor pushes on the bottom and the head of the baby to move it around in to the right position, then you have another CTG. It should NOT be painful and if it is they need to stop.
The risks are - Placental seperation (which means immediate CS)
-Rupture of membranes ( which can lead to augmentation of labour then puts you in the cascade of intervention)
- Cord entaglement (which can result in C/S)
- Onset of labour

the stats say that an ECV is effective in 50% of women who have it. of those 50% 95% stay head down.
Breech vaginal births are possible and c/s will put you and baby at further risk of complications then a normal birth.

You might need to organise someone to care for your DD as of your next appointment if the ECV does not go as planned.
You also do have a choice and depending on where you are i am sure i can help to find some advocates that will help you if you do not want to have the c/s you have been told you will have to have if he doesnt turn

Thanks glorious. Dd is at her dads from the 7/6 to 15/6 and appt is on 12/6 so have a few days leeway.

I'm birthing at gosford hospital (nsw central coast)

Last scan on 6/6 had his feet near his head under my left rib. He has been doing a lot of flips tonight so he seems to be having fun

Ive had a not so pleasant pregnancy so this is almost the icing on the cake. I had a long and traumatic labour with dd (43 hours) so really wanted this one to be "easier"

Thanks again for all your help
