RE: We're going stir crazy!
Gymboree is an option, but is very expensive. I am on their mailing list and the price is $153 for 9 sessions. Yikes! I have never signed up for a session, but several of us in my playgroup regularly go during "free preview week". Basically, the first week of the new session, you can take one class for free to try it out. There is one coming up, but I can't find my card. I am pretty sure it is the first week of September, but call your local Gymboree to be sure. Sarah likes the music class better than the regular class, but she is pretty easily overstimulated. Also, the music class might be easier with 2, since they are not roaming around in the large open area like the regular class does. I have also NOT been very impressed by the quality of the instruction at the Gymboree near me, so I would never pay to go there.
We live in Fairfax Co. in Northern VA and we have taken classes through our county parks service (which is very large and well organized). We took a baby swim class (really a water acclimation class) and these are GREAT because baby gets quite tired. But this would be hard to do with two. There are also what they call "Watch Me Grow" classes for babies of various ages, which are like Gymboree and are essentially facilitated, age appropriate interactive play sessions with mom and baby(ies). Many places offer classes like these (some health clubs, larger churches, hospital systems, etc.)
Do you belong to a playgroup/mommy group? If not, I highly recommend joining one. Mine has playgroup once a week, usually a lunch once a week, and we often do other baby related things (Gymboree, Signing with Baby, swimmimg class) and non-baby related things (Mom's Night Out, Book club) as well. Mine keeps me quite busy!
You don't say where you are in Maryland, but if you are close to DC and live near a metro, you could make a day of going into DC. Sarah loves the Metro and is kept quite busy by people watching. Small petting zoos are nice too. Sarah likes to watch the animals and likes to touch the rabbits and goats (depending on your hygiene philosophy this may or may not work for you, I just take lots of antibacterial wipes for afterwards).
