I recently relocated to Germany for my husbands job.. I had a home birth in the states with my second and was hoping to do the same however since the system seems to be different here and since my German is horrible I need help finding a English speaking midwife that can do home births..
According to the local midwives' association, these two midwives offer homebirths in the area you've asked about.
Angelika Behrens in Nürtingen, www.hebamme-behrens.de
Ulrike Merz aus der Hebammenpraxis Dettingen www.hebammenpraxis-dettingen.de
There are more in Stuttgart, I found http://www.hebammenpraxis-stuttgart.de/hebammenpraxis.html
Additionally, any OB/GYN should have a leaflet with names and adresses and services offered.
I couldn't find anything about languages spoken on their websites. Just contact them by phone or email. You can expect them to know enough English to at least discuss what you are looking for, though you will have to decide how much you need for your comfort.
