And now she’s in her crib, having learned how to sit up from a lying down position, and she’s just sitting there in the dark sucking her thumb… now she’s trying to stick her head through the bars of the crib… oh, and now the crying begins. We have a video monitor which is how I’m live-reporting her nap. Or her non-nap. Why she gotta learn how to sit up?
