Learning to talk
Parents who respond when baby "talks" help draw his attention to his own sounds. This makes talking more interesting and important to your infant.
Encourage him to practice talking by playing games with him. When baby makes sounds, repeat them back to him. Pause and give baby a chance to answer.
Your imitation excites him and may cause him to repeat the sounds. Keep listening! You may hear certain tones of voice and sentence patterns in your child's babbling.
Baby may have a sound, like "ba." that he uses to mean many different things. These "words" indicate talking isn't far away. Between 9 and 12 months, baby might have a real word or two mixed in with the babbling.
