I was fortunate not to have a child that couldn't live without their pacifier, but my daughter put us through h@#$// a couple of times when we couldn't find her Cow-cow. Cow-cow was a small stuffed nylon toy that I do believe looked like a cow at some point in its existence. (It is now a gray rag stuffed into my drawer of sentimental things.) She would not take a nap or go to bed without it. I was nearly late for my first day at a new job because I forgot to pack Cow-cow for the babysitter and I did not want to put the babysitter through the horror of my screaming daughter at nap time.
I think the frantic mother above will find the pacifier shortly.
