Parentese, which is how most people naturally want to speak to babies and toddlers, is higher pitched overall with wide swings in pitch when spoken.  This gives parentese its singsong quality.  Along with its high intonation(variations in pitch) characteristics, parentese allows for babies to pick up different speech patterns as well as distinct words, vowels, and syllables.

Parents all over the world speak in parentese, regardless of the language spoken.  Let your natural instinct and voice come out as you talk with your child.  Remember, communicating early and often is the best recipe for language development!
