I'm actually going to St V's for bubba in Feb. I've looked into the policy there and they actually prefer the baby to be with you in your room as the nursery is only "for sick babies". The mid doing my classes said the nursery is not a "well baby" nursery and it is more beneficial for bonding and first time mum education for the baby to be roomed with Mum. So I'm not sure how the mix up happened (although I intend to ask my mid tonight!). Try not to worry about it - it is a rareity.
I can recall when my sister was born the nursery had one of those windows (but that was almost 20 years ago!). I went and toured a hospital near me in Vic and they also had one of those windows in the nursery (but they had the curtains drawn). I think it depends on the hospital really...
