I would demand to see an OB, if you are not happy with that Ob you have the right to request a different dr, or even ask for the registar.

Make it very clear if you do not feel you are being properally listen to and looked after that you will be lodging a formal complain with the hospital and possibly the health minister.

You have rights in the public system, and you have the right to request a new dr and midwife. You also have the right to complain about your care until you are happy with it (when there is something wrong)

As nice and understanding as your SIL may be, it is about the health of her child, and i wouldn't hesitate to make a fuss about it.. Who cares if the midwive gets reprimanded, that is not your SIL problem. And even if they are right, and the baby is ok, your SIL still deserve to have her qns/concerns dealt with, as her emtional well being is just as important.

If the dr specifically asked about having the kidneys checked, i would be making a complaint about the ultrasound technologist also. Its not right that they have to pay to go private when it was requested for medical purposes.

I'm sure there is somewhere you can look up about patients rights.. I only know a lot of this as my mum is a nurse & midwife, and basically tells me to make a fuss when i'm not happy and not to take it lying down.
