Oh Gracie, like Lulu, I had a waterbirth at the Angliss, that's how Riv was born and I'm booked in for the next one too! They're great because you have one less thing to worry about, you know they'll stick with intervention-free birthing ideals. I also trusted them in that, if they did suggest intervention, it was because I needed it, and not cos they were bored and wanted to fiddle about. My midwife saw that I had my dh and my friend who's also a student midwife and just left me to it! She popped in every now and then (probably more than I noticed) and told me I was doing well.
I've heard they can get busy and I heard a couple of weeks before River there were heaps of births all at once and they shuttled a few over to the normal birth suites, but with Birth Centre midwives, but I had the whole place to myself!
Anyway, sorry, off topic and you actually asked Lulu, and I can't speak for her, don't know if her experience was anything like mine.
Where are you planning to have this bub Gracie?
