I miss her. Although it feels good to start work again, and to get things done with a little continuity (which is a rareity when you have a 15-month old around your feet all day), many times a day I stop and get the feeling I've forgotten something, or that I've left something somewhere, or that something is missing... And then I know, it's that little someone I'm missing.
And then, I realize I'm not getting a lot of continuity anyway, daydreaming like that, so I pick her up early.
