Since January, DH has been working from home about half the time. I don't always know when he'll be here and mostly I try to pretend he isn't here while I go about my normal day (that's so he can get some work done).
But one thing I love is that I can leave while Eliza sleeps. This morning, I took Michael and the twins to a summer movie ("The Bee Movie," which was totally stupid, by the way) and left Eliza in her crib. DH listened for her, but she didn't wake up until after we got back.
