Questions On Confinement Nanny

Hi mummies, this will be my first time hire CN, it's private CN. Previously my mum do for my confinement so I have not cure how it goes. My question is. 1 - do CN need to have her own room? My 2 elder kids each have their own room so I do not have spare room anymore. 2 - Nb sleep with CN every night? How about night need to breast feed or so? Or I just pump instead of breast feed.
