National Harbor is a nice place to stay, though I don't know if the Children's Museum is open right now. It was closed for a while, but it's been a long time since I checked the re-opening schedule and I can't remember. The only bad thing about National Harbor is the lack of public transportation. If you wanted to spend time on the mall and in museums (which you could for days), I would stay somewhere on the metro lines.

@Weagle: My parents took my son to the Children's Museum at National Harbor last week and had a great time. He's almost 2.5 though... I don't think it would be worth it for a 7 month old...

I'd probably vote Annapolis- it's a cute, walkable town, and you could also easily head over to one of the islands (Kent, St. Michael's) and walk around there too.

There's also Harper's Ferry- I've never been, but I've heard it's fun and there's stuff to do.

@Lozza: Good to hear! I'll try to plan trip to take LO soon.

I missed the 7mo part.... Yeah, I would just go to something that's appealing to you. The aquarium in Baltimore is cool enough, but it's expensive. I amend my recs to say either go to Annapolis or stay in DC... If you want an actual establishment a little more geared to your LO, the zoo is free.
