I hadn’t planned on including this song in the playlist, because while it’s a great one, it would never have occurred to me to sing it as a lullaby. But a few weeks ago, it came up in iTunes shuffle, and both my kids reacted to it immediately. My son wanted to hear it a second time. Then he asked for it a third time. Then a fourth. After nine repeats, we made him stop and go to bed. The next day he asked to hear it on continuous repeat for forty-five minutes or so. Evidently, it made an impression.
