Dear Hadley,
If you see a sleeping baby, he does not "need song." Similarly, sleeping baby does not "need paci." If you turn on a loud song and shove a paci into a sleeping baby's mouth, yes, he will wake up and start to cry. You don't need to tell mommy, "Baby cry." I can hear it. I promise.
Nevertheless, I love you and all of your overprotective mothering instincts.
Love,
Mommy
