Long before they can speak clearly, babies understand the general meaning of what you're saying. They also absorb emotional tone. Encourage baby's early attempts to communicate with you with loving attention:
Smile often at your baby, especially when he is cooing, gurgling, or otherwise vocalizing with baby talk.
Look at your baby as he or she babbles and laughs, rather than looking away, interrupting, or talking with someone else.
Be patient as you try to decode your infant's baby talk and nonverbal communication, like facial expressions, gurgling, or babbling sounds that could signal either frustration or joy.
Make time to give your baby lots of loving attention, so he can "speak" to you with his or her baby talk, even when you're busy with other tasks.
