Peoria is a GREAT place (well, okay, relatively) for birthing babies.
Pekin Hospital is Baby Friendly, though I think only one of the Peoria-area CNMs have delivery privileges there. And she is one of the more "medically-minded" CNMs. (Disclaimer: I birthed twice at Pekin. Once with the aforementioned CNM and once with a CNM who is no longer practicing, though her assistant is now licensed but doesn't have privileges at Pekin.)
Methodist Hospital (in Peoria) is working towards Baby Friendly. All the other CNMs have privileges there, IMO. And I'm pretty sure CAT insurance now covers Methodist.
I advise avoiding OSF unless she has need for medical management (which happens, in which case OSF is excellent.)
Peoria also has several CNMs who attend homebirths (yes, legally!) and I believe people have been able to get insurance to cover to some extent with the "distance" clause.
