I didn't get DS done (DH isn't done either) and I know in perth its quite hard to get a DR to do so?? I looked into it briefly but chose not to in the end.
I would ask your OB's about it if you are getting it done just to book someone to do it (there is also time after baby is born and if that time passes you can't get it done??) sorry, I'm not sure on all the facts, I just know people who have struggled to get someone to do it - no idea why!!!
