The torrent of language your baby has been hearing since birth is beginning to work its magic, although his or her understanding of words far outpaces the ability to use them. Your baby's babbling has turned to jabber and is probably starting to sound more like real words, phrases, and sentences. Your baby thinks he or she is saying something, so your job is to respond to it!
Your baby still comprehends more from your tone than from your actual words, though. He or she understands when you're pleased, so offer specific praise, such as "You did a great job picking up the rattle." The more you talk to your baby – while preparing dinner, driving, or getting dressed – the more he or she learns about communication.
Your baby's starting to understand the word "no," but won't follow this direction yet. For example, you can expect your baby to try to touch something even after you've said not to. It's best to use the word "no" sparingly so it doesn't lose its power to get your baby's attention. When you do say "no," follow it by removing your baby from the scene and introducing a new activity.
