Nursery troubles!!

Sierra • Expecting baby girl Evelyn, Sept. 2016❤️
This is the room I have to work with to create my daughters nursery.. Due in September but don't want to do it all last minute. It has extreme slanted celeings and stairs leading to outside.. The only place a crib will fit is where the half wall is. Anyone else have to deal with this and have any ideas?? Please help
