Remember, your baby is learning how people talk to each other.
You help your baby become a "talker" when you do these things:
- Hold your baby close so he will look you in your eyes.
- Talk to her and smile.
- When your baby babbles, imitate the sounds.
- If your baby tries to make the same sound you do, say the word again.
