I fully support creatively themed nurseries that reflect your personality and style. Why not? Your kid isn't old enough to know what they like yet...go ahead and impose a little bit of your own taste on them.
I think this nerdy nursery is totally awesome. It's Star Wars themed and I think it is pulled off very tastefully. The color scheme is consistence, it's not cheesy. It's all in the details. I kind of love it.
Well done, parents.
