when I had DS1 they did take some of hte babies off to the 'nursery' if the mum's desperately need a short "respite" (the 'nursery' was actually the room where all the towels,bottle warming stuff, and baby baths were - which had enough space for a number of cots LOL).
I had a hellish long first night with DS1 first night (he never slept - at all!), so the 2nd night they said they'd take him through to let me have a bit of rest, then bring him back when he needed feeding.
They wheeled him off, I dragged myself out of the bed, went and made a cup of tea, got back to my bed and they suddenly appeared back with him.
"sorry we'll have to leave him in here with you, he's too loud and is disturbing the other babies"
I was in for 3 1/2days, and he was the only baby for who the 'nursery' door was closed while he was being bathed.....I know because from my bed I could see the door)
