Make it a two-way conversation. When your baby babbles or makes sounds, respond by saying something back. 
 

Talk in a slow sing-song voice and repeat words often.
 

Copy the sounds your baby makes.
 

Ask your baby questions and then answer them. This helps your baby learn to listen and talk!
 

Let your baby look in a mirror and ask, “Who’s that?” then say your baby’s name. Point to her nose, ears, eyes, etc. Name each body part as you point to it.
 

Hold your baby close so he can look in your eyes.  Talk to him and remember to smile.
 

Talk through daily activities, step by step: "I'm filling up your bathtub. The water feels nice and warm. Let's use the yellow sponge to wash your toes!"
