Despite having more museums per square mile than anywhere in the country, Washington D.C. doesn’t have a museum dedicated just to kids. In our ongoing survey of the children’s museums of the East Coast, there’s not a single one we can reach by Metro. But that doesn’t mean that there aren’t kid-friendly spaces available. The Smithsonian is working to develop some exhibits that focus on small children, such as the Wegman’s Wonderplace in the Smithsonian’s National Museum of American History. On a visit a few weeks ago, we found it to be a cute area for small children, especially in the context of a larger visit to the museum.
