A day confinement nanny can work well if your space is tight, since she still handles the key daytime tasks like cooking your confinement meals, bathing the baby, and giving you rest during the day. The trade-off is the nights are fully on you and your husband, which can be really exhausting in those first few weeks especially if baby is cluster feeding. Some families do put the full-time nanny on a mattress in the living room and it works out fine, though it really depends on how comfortable both parties are with that arrangement and whether she is agreeable to it. I would say talk to a few agencies, be upfront about your space situation, and see what they suggest based on their nannies' preferences.
