Living in a 2 bedroom condo and expecting baby #2

So me my 7 year old son and my SO and our French bill dog live in a small 935 square foot 2 bedroom condo. We are expecting baby #2 whom will not have her own room so she will have to share our room. We currently do not have the finances to buy anything bigger at the moment and the cost of living in our home city is quite high. Does anyone else have a large family living in a small house? How do you make it work? Eventually my 2 kids may have to share a room but my son isn’t to keen on sharing his room with his sister when she’s older. I’m hoping by then we will be able to afford something bigger. My SO actually just got laid off from his job last week so that really put a damper on things. We’re just going to have to make it work in our small little shack for now. I’m worried that it’s going to be hard to fit all of the babies things in our room without making it extremely cluttered. I’m also sad I won’t be able to decorate a cute little girls nursery for her as I did with my son when he was born.
