Baby talk, motherese, parentese, mommy talk, infant-irected talk (IDT), or child-directed speech (CDS) is a nonstandard form of speech used by adults in talking to toddlers and infants. It is usually delivered with a "cooing" pattern of intonation different from that of normal adult speech: high in pitch, with many glissando variations that are more pronounced than those of normal speech. Baby talk is also characterized by the shortening and simplifying of words. Baby talk is also used by people when talking to their pets, and between adults as a form of affection, intimacy, bullying or patronising.
