That's really odd. If that's what the rules state no amount of publicity will change the outcome. Doesn't your OB work from a public hospital at all? Personally I'd be swapping to a public hospital or you could be up for a fortune with the likelihood of the babies being born early. You can still get a good relationship with a new OB - I've seen 3 (one for scans and amnio) and I've found them all great.
