Definately accept the bassinet as others have already said they are very useful in the first few months.
We had DS in our room until he was 6 months and will probably have DD in with us for at least 12 months. We are both deep sleepers so it easier for us to hear them when in with us and FionaJill made some really great points
Bringing a warm soft, cuddly beautifully smelling NB back to bed for those late night feeds is the best thing about having a baby. mmmm can't wait to be able to do it again.
I agree, i miss that smell
also "cosleeping" can reduce the chances of SIDS, but it is your bub & your house so at the end of the day go with what works best.

Just a had a thought - if you want to keep bub in their nursery get either a really comfy chair or a single bed so you can sleep in there if you need to.
