This is going to sound crazy, however I'm posting this in all seriousness.
We have all had those infants who are going through withdrawal or for some other reason get so worked up to the point where they are inconsolable. I have found that when I sing the song Found a Peanut to them they at least calm down enough to take the pacifier or a bottle. Perhaps I am crazy, some coworkers would agree, but my observation has been that this works for me in the majority of situations. It calms the infant down enough until some other more long lasting intervention can be started, whether it be to give meds, get a bottle ready, etc.
Now I don't know if it's that they are terrified by the sound of my voice or what, but that is the only song I have found works. Maybe it's the tone of my voice the song brings out, perhaps a different song for someone else. Thought this was an interesting observation to post and wondered if any of you have had similar observations. If not maybe you'll at least get a chuckle out of the idea.
