Can't decided on sleeping arrangement

I'm such a worry freak that this baby will come sooner then EDD. My lo was 7 weeks early and I had nothing ready luckily while LO was in the NICU I did tons of running around. This time it's a no-no for me! Our bedroom is a perfect size however we have a king size bed that just happens to take up everything. LO has own room, and for the first couple months I decided to hold off on letting her and her new baby brother or sister share rooms. I can't decided on a co-sleeper, rock n play, pack n play with bassinet or a mini crib!
