Three to Six Months
• Sounds begin to have meaning.
• A child begins to respond to “no.”
• The baby recognizes changes in a voice’s loudness and pitch.
• He or she starts to associate word meaning with sound.
• The baby listens to his or her own voice.
• Rhythm and music draw their own reaction.
• The baby shows an interest in toys that pair sound with movement, such as rattles, musical mobiles, or anything else designed to make noise when it moves or is moved.
• The baby demonstrates increased attention to more varied environmental sounds, such as a vacuum cleaner, a fan, or a door slamming in another room.
At the ninety-day mark, your baby is now ready to play. She is awake for longer periods of time, is more physically active and clearly enjoys interacting with you. She can now grasp objects and bring them to her mouth for more sensory exploration. If your play involves language, your baby is ready to experience that, too. At this age a child can create vowel- like (“a,” “e,” “o”) and consonant-like (“p,” “b,” “m”) sounds.
