“Hush, little baby, don’t say a word,” I sang to Abigail tonight. She had finally settled in my arms and her eyes had been closed about 30 seconds, long enough for me to hope we were done with the nightly struggle to fall asleep. Then she opened her mouth and began to sing, eyes still closed. For Abigail, singing is just like babbling except that she draws out the syllables and moves between high and low registers as she does so, like a scat singer. Her closed-eye singing was especially inspired. After a few bars she sleepily cracked an eye open for a moment, took a deep breath, and hit her money note: BAAAAAAAAAAAAAAAA BAAAAAAAAAAAAAA! Then she snuggled back down in my arms, quiet and still; sweet slumber had arrived.
