Parentese is the slower, higher-pitched, sing-song way adults naturally speak to babies, using real words and correct grammar. It is different from baby talk, which uses made-up words, and research shows it helps babies engage and learn language.

Key takeaways

  • Parentese uses real words with exaggerated tone and stretched vowels.
  • A University of Washington study found that coaching parents to use more parentese led to more baby babbling and larger vocabularies.
  • It works best as part of back-and-forth conversation.

What you can do

  • Talk to your baby face to face with a warm, lively tone.
  • Stretch vowels: "Look at the biiig dog!"
  • Pause to let your baby respond.
