Yeah if they are identical and there is any potential risk from TTTS they will suggest a C/S.
A lot of hospitals make twin birthing mummas have an epidural *just in case* the second twin doesn't descend or if they end up breech in labour
so that emergency C/S is a quick process. Mum wasn't 'allowed' to have them vaginally in Geelong, they were going to C/S her so she went to RWH.
The girls were born at 33 weeks gestation, not more than 15 minutes apart... labour was 4 hours (and they were trying to actively stop and slow it)
probably would have been quicker without the epidural!
