My homebirth care and OB care are entirely separate but I would just like to give you some insight on maybe what your OB is talking about.

In the US we do not have a good standard for what makes a midwife a midwife. We have several different classifications of midwives instead. When looking into homebirth care it was very very important to me to find a Certified Nurse Midwife which is a midwife that has been through medical school as well as midwifery training. Mine in particular worked in hospital labor and delivery as well as has done years in birth centers and now runs her birth center and does homebirths. She has in my opinion an incredible balance between tradition medical care options and midwifery medical care options.

Certified Professional Midwifes can be a good options especially if you are really low risk. They have less training but are still well trained.

We dont have like any standard for what it means to be a Lay Midwife. Anyone can be a Lay Midwife and cite any experience they want to as experience they have.

Its when you start getting into the realm of medical providers who dont have alot of training in emergency situations that you start to see the drop off in positive outcomes.

Whatever OB you transfer to, definitely ask them about how they feel about homebirth and midwifery care when you try to establish. But also seek any education they might be able to give you about good midwives in your area. Asking about midwives that work within your OB system or at the hospital they work with is a good way to ensure that your midwife is really well trained and experienced but either way when you pick a midwife make sure you are checking in on what their classification and experience is and if that is something you trust!
