Since you only have just the one window I would keep it as light as possible. It would look nice with just a white mini blind and a cute valance topper. I also really like the cute fabric shades that keep the window nice and simple and don't over power the room like what I attached. Best wishes for you and the baby!
Nursery is far from finished, but what length curtains would you put in this room? Floor length or shorter? It is a small room but the ceilings are fairly high for a bedroom. We are going to put a glider and side table to the right of the window. Btw the wall color is lighter than it appears in the photo ;)
