Doctors

Today my wife and I went in for a 2 week check up with a new O.B, then in 2 weeks back to her main O.B then we will probably get set up with a different O.B before getting back to our regular doctor. I understand why they put expectant mothers through a round of musical doctors. However they should fair warn the mother ahead of time like when they first agree to be the main doctor of said mother. That way the parents the mothers especially are not thrown off by the sudden changes.
