Have you had any success finding a matching chest of drawers? MIL bought us the changing table that was also in walnut and it doesn't match really well (probably since we bought them at different times the stain was slightly different or something), but it'll work.
I've been trying to find a chest of drawers to match and not having any luck, so I bought a 3 shelf bookcase to put books, a lamp, and some storage bins on. It also wasn't the same color but close enough, and it was on sale for $12 so I figured it couldn't hurt!
Re: Those who bought the Graco Lauren crib in Walnut
This is essentially what we are doing. We already have a dresser and once we get the color scheme set for the nursery, I am simply going to paint it a color that will match, most likely a white or a green color.
