The black sofa could be considered a neutral, and therefore will go with just about anything. Do you like the white and gray, or are you looking for color? Bright colors? Subtle colors? Also with a baby I would surely want an area rug for her little knees. In this first picture you can see pops of red were added for color: [houzz=https://www.houzz.com/photos/2007-aso-decorators-showhouse-and-gardens-contemporary-living-room-atlanta-phvw-vp~26704] In the second picture, a monocrhomatic color scheme with a soft area rug: [houzz=] And in the third picture, yellow was added for interest: [houzz=]

Thank you for your suggestions everyone. I am going to layer it with another solid rug and use it in the living room. My living room neds a bit of colour and I thought this would be perfect. Breaks my heart to think that I may have to put it elsewhere.

Have you ever thought about floating shelves? I think pairing a few floating shelves together would look great and would free up space in your living room. I really like the Eugene floating shelf from Bryght and I think it would compliment your existing pieces. http://www.bryght.com/product/160/eugene-cocoa-shelf

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.
