Ideas for nursery decor?

Hello! I am 24 weeks pregnant with boy #2, and I am absolutely stumped with how to decorate his nursery. My husband doesn’t want to repaint the room, which I get even though I’m not a fan of the color - money could be better spent other places - but I am at a total loss at how I can decorate with this color scheme. The white on the side is the color of the door frame and closet doors, and the grey (depending on the light it has a slight purple tone to it) is the color on the walls. Any ideas?
