General Suggestions for Language Development

  1. Imitation - By imitating what your child has said, you are showing your interest. It is also a way of confirming that you understand what he/she said. To imitate, repeat his/her statement back using correct grammar and pronunciation. This will let him/her hear the correct form without saying he/she was wrong.

  2. Expanding - In response to your child's initiation of interaction, you can expand what he/she said by adding more words to make the sentence clearer. For example:

    Child: Daddy
    Parent: Daddy help
    Or Child: Doggie run
    Parent: The doggie is running
    Child: Doggie
    Parent: He's soft or touch his fur

  3. Talk about what you and your child are doing - The moment to talk about experiences is as they are happening. This is when they are most meaningful.

  4. Be animated - If you are enthusiastic and entertaining, it makes communication more fun and keeps your child interested in the topic. Use facial expressions (e.g., smiling, nodding) and vary intonation in your voice.

  5. Ask questions - If you can't understand your child, repeat what he/she said with questioning intonation in your voice. This will encourage him/her to clarify what he/she has said. If this doesn't work, guess at the message. This confirmation will increase your child's self-confidence,

  6. Encourage interactions - Use non-verbal behaviours such as getting down to the child's physical level while playing or talking, do things that interest the child, encourage participation and pause to allow your child time to respond.
