I geuss that knowing your ob is an issue but depending on the model of care you choose in a public hospital it is possible to have your baby delivered by someone you know. If you can access a team midwife service you will see the same group throughout your pregnancy and one of them will deliver your baby. I geuss I'm lucky to be near a hospital that offers a range of options in terms of care.
I felt a bit sorry for the other lady in my room she was from the country somewhere and she had been airlifted in because of complications during her labour. It must have been awful to give birth in such an unfamiliar environment so far from home.
