If your child says “Ba,” repeat the sound back to them. Then add on to it, “Ba, ba, ba.” Do they try to copy your sounds? Add a new sound next, “Ba, ba, MA.” Do they notice the change? Do they try to repeat it? Go back and forth repeating each other’s sounds and building on them.

Even conversations with only sounds encourage communication by your child, using sounds and actions to talk to you. Changing the sounds helps them pay careful attention to the differences between sounds—an important step in learning to talk.
