This blog is full of great places to bring your kids in and around D.C. Entries are placed in a Google Map so you can figure out what is close to you and get directions through your smartphone. All activities have been vetted by our 2 year old. Please send your suggestions!
We just picked this up at Franklin's General Store in Hyattsville. It is a cool combination of building toy, as well as musical instrument. For only $10 you can't really miss with this one.
