Are doulas accepted in hospitals?

I have been a doula for over 15 years and doulas are in every hospital I know of.  We work at cultivating a positive relationship with the staff at all the hospitals.  It was a bit more challenging in the beginning but now we are widely accepted.  Often when a client has a doula the nurses are happy as they know the new mom and dad are educated on birth and has the support during labor, delivery and postpartum.
