Recall that scientists have discovered that babies attend to the rhythms of speech. This is one of the reasons why baby talk, with its singsong properties, is so attractive to babies. Try saying something rotten to the baby in your nicest baby talk, something like “You were so bad today!” Then try to say something kind in a rotten voice, such as “You were so good today!” You will get a chance to see the baby respond to the cadence of the speech and not the message.
