Success!! I got her to call her her mw. Shes going in this afternoon, will update later. Thanks for the help :-)
Oops! I was typing at the same time you were posting, hehe!

Well done to your sister for calling her midwife; hopefully all will go well for her and she will be having a beautiful birth experience at the birth centre about 20 weeks from now!

Let us know how it all goes!
