It's not surprising that babies can learn how to sign. Both their understanding of language and their motor skills develop much faster than their ability to speak. And they love to mimic: Most babies, for example, discover how to wave and point long before they can say "bye bye" or "look at that!"

Your new baby's first year is like a roller-coaster ride... thrilling at times, but with the odd anxious moment thrown in. As your baby grows, she becomes a little person in her own right and from her first coos to first words and first steps, she'll meet a whole range of magic milestones.
