Listening & Speech

Listening and speech development builds over time. These observations from AYJNISHD describe examples of auditory responses and speech and language development across early childhood.

AYJNISHD reference: 9 to 18 months

Auditory Response

  • Looks up when called
  • Understands words such as “no”
  • Responds to simple commands

Speech & Language Development

  • Uses their voice to get attention
  • First words may be heard during this period
  • Imitates some sounds made by others
  • Gradually builds a vocabulary of meaningful words by 18 months

Have concerns about listening or speech?

If you notice a persistent concern about your child's response to sounds or speech and language development, consider discussing it with a qualified healthcare or communication professional.

TalkPebble guidance

Support for everyday moments

TalkPebble-created ideas for turning everyday moments into opportunities to connect.

What this can look like

  • Your baby may repeat a favorite sound, lift their arms to ask to be picked up, or look for a toy that fell.

Try it at home

  • Repeat a sound your baby makes, then add one simple word.
  • Read a picture book and name the picture your baby is looking at.

What to say

  • “Ba-ba-ba… book!”
  • “Up? You want up.”
  • “Where did the spoon go?”

What to notice

  • Repeats sounds
  • Lifts arms toward you
  • Looks for a dropped toy
  • Looks when you call their name

Why it helps

Naming what your baby notices or communicates helps connect sounds, gestures, and familiar moments.

Try a TalkPebble activity

  • Wait for Response

    After you say something, count slowly to five in your head. That quiet space gives your child room to take their turn without feeling rushed.

  • Reading Together

    Follow your child’s lead instead of every word on the page. Talk about what they point at, and let them turn the pages at their own pace.

Keep practicing with TalkPebble

Use simple everyday activities to build on the moments you are already sharing.
