Your friends choices for model of care may be wrong for you but it might be right for them. I would point them in the direction of some good unbiased information and leave it at that. And try to remember that even faced with all the same information you were faced with your friends will not necessarily make the same decisions you have.
Well said hun. My first birth was a high intervention birth BY CHOICE and I know I would have told anyone telling me it was the wrong choice (either directly or inadvertently) would have not been greeted with a nice response.

I think offering advice IF asked, sharing YOUR story without obviously shooting down their way (if it's different to yours) is the best way.

Remember not everyone in life wants the same thing plus I think private OB/private hospital stats are very very hazy because you MUST take into consideration people's choice. It isn't as though every OB would prefer you to have a scheduled c-section
