Oh, how true this is. I am in charge of putting both the two year olds and the three year olds at my center to sleep. Inevitably, there will be one child who is overcome by the sorrow of not having her mother with her at that very instant, and I will spent an hour consoling her and speaking to her soothingly. Eventually she'll drift off to sleep, a mere thirty minutes before her mother shows up to get her and wakes her up again. Nap time, understandably, is not my favorite time of day.
However, once all of the children have listened to a few stories and drifted off to the sweet sounds of gentle music, I can just wander around and gaze at their small, sleeping faces, so sweet and innocent. There is nothing comparable. Forgotten is the biting incident of yore, and the fist fight that I had to break up at risk of life and limb. They are all calm and sweet in sleep.
