We went out to dinner on day #3! We've tried to get out of the house every other day or so, because, frankly, we were going absolutely stir crazy! Sometimes we'd just walk to the grocery store around the corner just to get some fresh air.
Our strategy has just been to keep DD as warm as possible, bundle with hats, layers and blankets if we have her in the stroller, and we keep the covers closed so no curious or overly friendly hands can touch her. Otherwise, she's right next to me in the Moby (which is awesome), where she is warm, snuggly and safe from any ooglers.
