Nurse Lovechild, Tommy Thumb's Song Book (1815)
“ The first Songs are very suitably compos'd for a Baby, but pray be careful, not to sing them too loud; lest you frighten the child, when you design to lull it to sleep, or divert it; for you know, great care ought to be observed as to the early sense of children, some arriving to a knowledge, and notice of animals and their sounds, much earlier than others. ”
